"If you forgot the answers to your Apple ID security questions" click here --> https://support.apple.com/HT201485

If you see the message "not sufficient information", read this link:

Security and your Apple ID - https://support.apple.com/HT201303

"Without proof of your identity ... and other carefully selected criteria(1), Apple Support can't help you perform any actions on your account." If you are still using security questions (see below) then you knowing your security question answers is the exclusive way, apart from potentially "other carefully selected criteria", of proving to Apple that you are the owner of that account.

(1) E.g., "In certain cases, Apple might also use your payment information to help verify your identity. You might need to verify your payment information to reset your Apple ID password" - https://support.apple.com/HT208683

It may ultimately prove very difficult to find satisfactory resolution to forgotten security questions if you get the "not sufficient information" message (e.g., https://discussions.apple.com/thread/252410816 ). For quite some time now Apple has been very strongly urging users to use Two Factor Authentication instead of security questions. --> https://support.apple.com/HT204915 "With two-factor authentication, you don't need to remember any security questions. We verify your identity exclusively using your password and verification codes sent to your trusted devices and phone numbers. When you enroll in two-factor authentication, we keep your old security questions on file for two weeks in case you need to return your account to its previous security settings. After that, they're deleted."

Here are two methods that are relatively similar for possibly recovering from "not sufficient information" by signing up for Two Factor Authentication at this stage:

Apple does have "Account Recovery when you can’t reset your Apple ID password" ( https://support.apple.com/HT204921 ) which it specifies is available for "when you don’t have enough information to reset your password." However, it also states it is "if you use two-factor authentication" which you may not be if you are still using security questions. You can investigate if this is even available to you.

With that in consideration you can try to "Contact Apple for help with Apple ID account security", click here --> https://support.apple.com/HT204169 If the online option does not resolve the problem I suggest trying to get a personalized response with a chat or telephone call. To talk by telephone: Contact Apple for support and service - Apple Support --> https://support.apple.com/HT201232

For other support options, including those if your country does not have telephone support, click here -->: https://support.apple.com/choose-country-region To chat, choose any topic, (not Apple ID) continue working your way down options until you find one with chat support, then ask to be redirected.

(Note: If your country is not listed, there may be a support option at the end of each region section for "other".)

If you have a forgotten/unknown device passcode, or have a disabled device, unfortunately you have no option but to erase the device. However, you can eventually restore the data and settings from a backup you made before the device was disabled. You must have a computer to use the method below. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider. You can also use a PC with iTunes. You will likely also need your Apple ID and password. All Apple mobile devices follow the same general procedure but the link below and other links off it provide model-specific instructions:

If you forgot the passcode on your iPhone, or your iPhone is disabled", click here --> http://support.apple.com/HT204306

Here is a related video which to me has more complete and clearer instructions: https://www.youtube.com/watch?v=7s8-zLG9ySQ

Steps:

1. With the device disconnected from a computer use the model-specific instructions in the links above to shut down the device.

2. Connect it to a computer with Finder or iTunes (Mojave or earlier, or PC).

3. Restart into recovery mode (black screen with a cable indicating attach to computer).

4. When prompted, click "Restore" to erase data & settings, and update system software. May take some time.

5. Set up your device ( https://support.apple.com/kb/HT202033 ). Partway through you are offered the opportunity to restore your data and settings from a backup, or you can do this at a later stage ( https://support.apple.com/HT204184 ). Even if you have no backup, if you were using some iCloud services to sync items such as Contacts or Photos those may reappear once you sign back into your iCloud account --> Set up iCloud on your iPhone, iPad, or iPod touch - https://support.apple.com/HT208681
