You mean the 2023 column on the Income or Deduction screens are filled out? Try transferring from your 2023 return again. Are you using the Desktop program or the Online version? What did you use last year?
Start a new return (File - New), does your 2023 return show up to transfer? You need the file ending in .tax2023 to transfer into 2024. It should be in your Documents then in a Turbo Tax folder. Or search your whole computer for all files ending in .tax or .tax2023.
If you don't have the main .tax file you might have one that starts with a Tilde sign ~ like "~your name.tax2023". That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
Here's an idea. Do you still have 2023 installed? Try opening 2023 program and see if you can get your 2023 return to show up in it. Go to FILE - OPEN. And see if that is the right one.
