Unfortunately, once a TurboTax account is created, it cannot be deleted. 

 

However, if you haven't submitted payment or registered your product, you can follow these steps to erase your data:

 

1. Open your return 
2. Select Tax Tools from the left menu
3. Choose Clear & Start Over
4. Select Yes to confirm
