Yes, you will need to amend your 2019 tax return to report the corrected W-2. I'm sharing a link to a TurboTax FAQ explaining how to amend your 2019 TurboTax Online return. Follow the instructions carefully, as they are specific. If you file a state return, remember to amend it, as well. Please note that you'll need to print and mail your amended return. Don't forget to sign the return(s).
