How can I enter new payment information in itunes and the app store? My account has been locked because my credit card information is not up to date.

Hello alkeef,

It looks like no one has responded to your question. Here are a couple things that might help others answer your question:

1. Are you seeing a message that your Apple ID is disabled? What is the exact message you are seeing?
2. Do you have a payment method enabled already?
3. What device(s) are you seeing this on?

Please provide as many details as you can and thanks for using the Apple Support Communities!
