In order to open a .tax file you need to have the program installed on your computer. Since you do not have the CD you can contact TurboTax. To get a replacement CD for TurboTax 2016–2018 software (or 2019 software beyond the 60-day replacement window), contact us for a downloadable copy. If you don't already have a download account with us, you'll need to set one up.
A tip is to also save your tax return as a PDF file, then you can open and print it in Adobe Reader
