Do you need to amend? Or just fix something and file it? You only amend a return that was first filed and accepted. If you still need to file the original return you can print it out and mail it.

If you can't get the side menus to open up to access the prior year..... You need to start entering some basic Personal Info in 2023 for the side menu to open up. Just continue a little ways into 2023. I had to go though about 12 screens.
