Have you tried opening your .tax2023 file in the 2023 program to see if it looks correct? If you saved your tax file to a cloud type storage last year, then downloaded it to use this year, it may have become corrupted.
You can also try using a 2023 backup file (you probably have a couple of them). Move the file to your desktop, then transfer it into 2024. You can 'start a new return' in 2024 to try this.
