First try to open the .tax2019 file from the hard drive not the backup. So you may need to copy it from the usb drive first. Can you start a new return in the program?
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 Tax Return).
Then go to FILE -Open and find your return.
