And you can transfer from 2018 that's on your computer now. So be sure to save the data file ending in .tax2018 on a flash drive or somewhere so you can transfer it into the online version.
Also before you get get rid of the old computer you should save each year as a pdf file if you you haven't. And then save all the .tax and .pdf files for backup.
Your tax files end in .tax or .tax2015, .tax2016, .tax2017 or .tax2018 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 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 or print your return in the future like to get a mortgage or loan, etc.
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.
