The same problem still exists in the Turbotax Deluxe for Windows software for the 2023 tax year. The AGI amount is carried over incorrectly from the original return to the amended return. The workaround is to edit the 1040X form manually and copy over the incorrect amounts from the original return.
Since Turbotax makes claims of accuracy for their software and since this has been reported repeatedly by many users over the past five years, it is disappointing that (1) this cannot be fixed from one year to the next and (2) that there are no comments from the Intuit company on this forum.
I did not call tech support to report a bug, since other users have reported that this is useless and leads nowhere. I write code myself, so I know how easy it is to get something wrong, but I also realize that my code is useless (and I would never give it to others) if it creates the wrong output.
