The W-2c changes the original W-2. First undo the changes that you made in the state returns, or, if you are using the CD/Download TurboTax software, start your amended return over with a fresh copy of your original .tax2021 file. Then, to make the changes for the amended return, go to where the W-2 is entered in the federal section and replace the amounts from the original W-2 with the corrected amounts from the W-2c. The changes in the state amounts will flow to the state returns.
If you have further questions about entering your W-2c or amending your tax return, please tell us whether you are using TurboTax Online or the CD/Download TurboTax software.
