can I get my 2023 depreciation file transferred to 2024?

Didn’t you transfer from 2023 when you started 2024?   Did you use the Online version or the Desktop program for 2023?   Did anything transfer?  If you find the right 2023 file to transfer you will have to start a new 2024 return, go up to File-New.  You can only transfer at the very beginning before you start 2024.

This is mainly for Schedule C but can also apply to Schedule E.  If you used the Desktop program last year, see if you have another .tax2023 file on your computer.  

Or maybe last year you marked the Schedule C as FINAL in Turbo Tax?

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 your schedule C is in it and if it's marked as finally disposed.  Or any Assets were disposed or sold.

Then save it again with a name and place you can find.  Go to File - Save As.  Then start a new 2024 return and transfer from the 2023 file.
