Can’t delete old appleID

Constantly interrupted to put info in for 10 year unused appleID my daughter used to have. No one remembers the Pw. I cannot delete it, because it isn’t appearing on my users and accounts screen. Another thread shows I should delete purchases made by that account. But there is no screen I can find showing all purchases that could be locking this up. I don’t wanna reset the whole system as there are many apps that have unique passwords and it will be a tedious waste of time to have to plonk them all in again
