You don't need to delete an account. You have two options, you can clear and start over or you can begin a new one with a new user name.
You can't combine accounts.
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.
