Without your ID to recover it, your way out is to create a backup then DFU the phone in Recovery Mode.
You cannot simply erase the phone because it demands screen time passcode.
If you restore the backup and screen time is still locked you will have to DFU and start from scratch. How you manage data recovery will depend on where you saved it.

If you don't have a Mac or PC or you are nervous about these drastic measures then borrow one or contact Apple Support
