When you click "Amend a Filed Return" on the first screen when you start TurboTax, the returns that you have filed are shown at the top of the screen under the heading "Amend a Tax Return You Filed This Year." You have to click on the return that you want to amend, then click the Amend button that appears on the return that you selected.
If you don't see the return that you want to amend, click "Find a Tax File" to find the .tax2023 file for the return and open it.
