On the Tax Home screen, scroll down to Your tax returns & documents and select the year (2023) you want to amend.
Select the Amend (change) return dropdown, then Amend using TurboTax Online. If you're told to amend your return via TurboTax Desktop, follow the steps for TurboTax Desktop instead.
Continue through the screens, make the changes you need to make, and carefully answer the remaining questions to finish amending your return.
