how can I print a copy of my 2017 return? I have a tax2017file.

You would need the 2017 Desktop program installed and updated to open it.   But 2017 is too old to get or install.   Where did you get the .tax2017 file? 

Sorry you can’t install old programs.  They only support the last 3 years.   If you can’t download or open the pdf file and only have the data file ending in .tax20yy you could try the TaxPrinter service (not connected with Turbo Tax) to convert a .tax file to pdf at

OR get a copy from the IRS -
