To correct a return that you printed but did not file:
- In TurboTax Online, sign into your account.
- Select Tax Home in the left menu.
- Scroll down to Your tax returns & documents.
- Select 2018, and then select Add a State (you're not actually adding a state, this just gets you into the right menu).
- Make the corrections needed and finish your return.
**If you already mailed your return, don't e-file. This can cause problems with the government, including refund delays.
