Well you won't be able in install 2019 again anywhere. So if you still have it installed on the old computer use that to amend 2019. Same for 2020 if you can't get it installed on the new computer.
Then for 2020 onward......
What I would do is just copy the whole Turbo Tax folder that is under your Documents. That should be where the .tax files and pdf files are stored. Copy that folder to a flash drive or best yet is to burn it to a CD or DVD and then you will have a backup of them. Then on the new computer copy the folder (or files) from the flash drive to your Documents folder.
The programs need to be installed from the CD or download them again. You don't need to install them unless you need to amend or open a return. They only support the last 3 years so you might not be able to update older years or download any state programs you need.
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.

You only need the 2022 file ending in .tax2022 to transfer into 2023. Have you installed 2023 yet? Oh, how did you do 2022? It won't work on Win8.1. I had to get a new laptop to do 2022 also.
