Your post said you are working on your 2020 tax return. I assume that is not a typo so you are using 2020 TurboTax CD/Download.
The easiest solution is to start a new return.
- Select File in the top left
- Then New Tax Return
The other option would be to go into your return and delete all your wife’s income. Then go into Personal Info and edit Your Filing Status to Married filing separately.
