I am trying to amend my 2021 return and I am using the 2021 software, but when I click to edit my W-2, all I get is a blank screen.

If you are using the TurboTax 2021 desktop editions for Windows -

Save the tax return and then close the TurboTax program

Right click on the TurboTax icon

Click on Properties

Click on the Compatibility tab

Check the box Run this program as an administrator

Click on Apply and OK

Start the TurboTax program again.  Continue the return and see if the problem persists

If you are using the TurboTax 2021 desktop editions for a Mac -

Contact TurboTax support for assistance.
