It is not possible to pay state taxes due out of a Federal refund. There's no way to guarantee that the IRS would even approve a Federal refund. The only thing that can be paid out of a Federal refund is the TurboTax product fees. State taxes have to be paid by whatever method your state allows.
If the state changed your return, you should receive a letter at some point from the state (not the IRS). Or you can phone your state tax agency and ask them what is going on as far as your state return.
