If you have a .tax2023 or .tax2022 file you need to have the Desktop program for that year to open it. You can transfer a .tax2022 file into the 2023 Online version but you would have to start 2023 over.
You can buy the 2023 Desktop CD or the Download program here,

Then After you get the program installed the first thing to do before you open your tax return is to update the program and install any state programs you had. Then open your file. So you first might need to start a fake return to be able to download the state program (go to FILE - NEW). Enter some basic information, then go to the state tab and download the state program. Then try to open your existing return, go to FILE - OPEN
Or you could get the print out from your friend and mail your return.
