Try these steps, with testing touch ID with each in between step

Make sure you have the latest version of iOS or iPadOS.
Make sure your fingers and the Touch ID sensor are clean and
dry.* For the Touch ID sensor, use a clean, lint-free cloth to wipe off
any dirt or debris.
Your finger should cover the Touch ID sensor completely, touching
the surrounding metal ring. While Touch ID is scanning, you
shouldn't tap too quickly or move your finger around.
If you're using a case or screen protector, make sure it doesn't cover the Touch ID sensor or the surrounding ring.
Go to Settings > Touch ID & Passcode and make sure that
iPhone Unlock or iTunes & App Store is on, and that you've enrolled
one or more fingerprints.
Try enrolling a different finger.

If it is still not working, you need to contact Apple Support for servicing.
