You will have to amend your return for 2020 to correct the W-2 entry you made. If your tax does not change after you enter the corrected W-2 form, you do not have to file the amended return.

You can file an amended return using TurboTax for no additional fee. You will see the option on your Home Page in TurboTax, then under Your tax returns and documents, look for an option to Amend/Change your return.
