How come you have the pdf file and not the .tax2023 file? Did you only make a backup of the pdf file? Or how did you get the pdf file? If you scanned your return to make the pdf that won't work. You need the actual pdf file made by the program. Turbo Tax also saves the .tax2023 file. 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.
Also the pdf file won't help you very much even if it transfers from it. The pdf only transfers your name, address, ssn and AGI, not anything else like depreciation. You might as well start a new 2024 file and enter everything by hand if you don't have the .tax2023 file.
