Can I clear my state return and start over?

Yes, if you have not e-filed or mailed your tax return and you need to make changes follow these steps:

1. Sign into TurboTax if you haven't already.
2. On the Tax Home screen, scroll down and select Add a State (don't worry, we're not adding a state)
3. Now you will be able to access your tax forms and worksheets.

Thanks. I know this trick. And wonder why I can't do it in more convenient way.

But anyway it allows me to make amendment, but not fix existing tax and asks me about amendment reason etc. And eventually it allows me to print amendmend form, but not just form 540

@sbrytskyy If your return was already filed, your only option would be to Amend. Please see the directions below for filing a state amendment. When finished, we'll provide printing and filing instructions for the amendment. Your state may take several months to process it.
