I have purchased the program for both years - 2017 and 2018 (CD version, and I have downloaded updates). For some reason it is asking for a .txf file instead of a .tax2017 file. I am guessing that txf might be for Windows, but I have always used Mac computers, and I have the prior year file (.txf) on the same computer where I installed the 2018 Turbo Tax Premier Program. What gives?
