How do I cancel an amendment to my 2020 tax return made in error?

To access your current or prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/

 

When you sign onto your online account and land on the Tax Home web page, scroll down and click on Add a state. 

This will take you back to the 2019 online tax return.

Click on Cancel Amend on the left side of the screen.

 

The original return has already been filed and the refund received.  I got additional 1099B information  that  I erroneously entered in thr wrong spot.

You can delete the 1040X and start over again.  To delete an individual form, please follow these steps:
