How to remove a child’s account
I need to remove my child’s old apple id
iPhone 14 Pro Max, iOS 17
Question marked as
I take it this is a no longer used Apple ID that you want to remove entirely from your account.
If the Age on the account is more than 13 years old you can simply
Follow the steps under "Remove someone from your family group"
Leave Family Sharing - Apple Support
If the Age on the account is less than 13
You can request deletion of the account (from that account)

Or move the account to another account(if you have a spare account laying around)
Move a child to another group using Family Sharing - Apple Support
If you are still unable to get it resolved on your own you might want to
Contact Apple for support and service - Apple Support
Good luck!
