If you have already filed your state return, and it has been accepted, you would have to prepare an amended return to make any changes. Please see this TurboTax Help article for details: I need to amend my state return - TurboTax
If you have filed your federal return and now need to prepare your state, you can follow the instructions below:
- Sign in to TurboTax.
- Under Your tax returns & documents, select Show, and then select 2020.
- Now select Add a state (this reopens your return).
- Select State from the left menu (on mobile devices, tap in the upper-left corner to open the menu).
- On the Let's get your state taxes done right screen, select Continue and follow the instructions.
