Greetings ovy240,
Start by seeing if you are able to sign into your Apple ID using any of the following links, to isolate the issue:
"Use your Apple ID to sign in to Apple websites.
If you're already signed in to your device with your Apple ID and your device has Touch ID or Face ID, you can use it to sign in to iCloud.com or appleid.apple.com." Sign in with your Apple ID
Consider offering additional details to help the community guide you to a resolution.
- What exactly is happening vs what you expect to happen?
- Any error messages?
- Can you access your Apple ID anywhere?
Best wishes.
