Redo my tax return if I haven’t filed yet

As long as you haven't submitted payment, deducted the TurboTax fee from your refund, or registered, you can erase your return and start from scratch in TurboTax Online.

1. Sign in and select a topic to continue your return.
2. On the next screen, from the left-side menu, select Tax Tools, and then Clear & Start Over (select the menu icon in the upper-left corner if you don't see this menu).
3. Answer Yes in the pop-up to confirm.

When you log in  ... if  you are not given the option to continue the return AND you have not mailed or efiled the return yet,  then scroll down and click on ADD A STATE to let you back in the account then you can make the corrections needed   or   clear & start over if you have not registered the account yet.
