I"m trying to delete something for the "state loan repayment tax credit worksheet because I don't qualify for it. It won't let me edit nor delete?

Deleting your state return is a fairly straightforward procedure. Please see the TurboTax Help article How do I delete my state return in TurboTax Online? for guidance.

However, if you’ve already paid your state fees, you can’t delete your return.  You can start over by selecting Start Over next to your state return on the Status of your state returns screen.
