You can delete your TurboTax Online state return
as long as you haven't paid for it yet (or registered in a free version):
- Sign in to your return, if you're not
already signed in.
- Click State Taxes near
the top of your screen and proceed to the Status of Your State
Returns screen.
- On that screen, click the Delete
link right next to the price, and then Yes.
- If you already paid (or registered),
you won't see the delete option.
- Instead, you'll see Edit Return
and Start Over, neither of which will remove your state return.
