Why can’t I get into my Apple ID? In setting it’s lightened so I can’t even click it and I don’t know why?

Have you checked Settings/Screen Time for any restrictions?

Do you have access to another WiFi network where you can try? That has worked for several people.

Try a restart.

Try a forced restart.

If necessary

If there are restrictions in Screen Time that are preventing access, you will need to restore the device to factory settings. Do not restore from a backup made when the Screen Time code was active.

If there aren't restrictions in Screen Time, do a backup and try a factory reset. Then restore from your backup.
