@viji-sethuraman- The first paragraph might not apply to you if your old computer crashed. You only need the file ending in .tax2019 to transfer into 2020.
For Windows. Your tax files end in .tax or .tax2016, .tax2017, .tax2018, .tax2019 etc. They should be in your Documents in a Turbo Tax folder. You should also have the pdf files of each year. Or search your computer or backup for all files ending in .tax. Also if you haven't done it, I would open each year in the program and save it as a pdf file, go to FILE - SAVE TO PDF so you don't need the program installed to view your return.
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.

After you get the program reinstalled 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).
You reinstall the federal program -> run update -> download the state program -> run update. Then make sure the .tax20yy file is moved to new computer. Do not Open that file from the transfer medium.
You can't transfer the programs. They have to be installed from the CD or Download.
You don't need to install the prior year programs unless you need to amend that year.
