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.
- Sign in and select a topic to continue your return.
- 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).
- Answer Yes in the pop-up to confirm.
Note: If you're in the TurboTax mobile app, you'll need to sign in to TurboTax Online from a web browser to clear and start over.
