You can delete the state and start over IF you haven't paid for it yet or registered it (in the Free edition). Click State in the black bar on the left of your screen. On the Status of your state returns screen, click Delete next to your return.
If you want to start both the federal and state over, click Clear and Start Over in the black bar on the left of your screen. You can do this only if you haven't paid for the return yet.
