For 2014 only, the print functions for Mac were moved from the TurboTax software package that runs on the computer to software on a TurboTax server (this was due to a 3rd party licensing issue) . That required an internet connection to the "Secure Print Service" in order to convert the raw TurboTax data into a printable pdf file. Without the "Secure Print Service" it is not possible to print 2014 from a Mac.
TurboTax no longer supports any software version prior to 2015 (and 2015 will be dropped after the extended Oct 15, 2019 date).
It would appear that the "Secure Print Service" is no longer available so it is no longer possible to print 2014 with a Mac.
Or hey! Try to find a Windows computer. The .tax files can be opened by both the Windows and Mac programs. But you would have to install the 2014 program which might be impossible. Even if you have the CD you wouldn't be able to update the program or download any states you need. Unless you know someone with 2014 still installed on Windows.
So maybe that www.taxprinter.com would work it they use Windows.
Sorry for the delay. Taxprinter.com did work! It cost me $79.95 and took 4 business days, but the company emailed me a PDF version of my 2104 tax return for Federal and State, and I was able to print and file my returns. Thank you very much to @macuser_22 for the great suggestion!
This is actually ridiculous. I got a note from IRS last month saying they never got my 2014 return (they have all years prior and after), and I didn't waste at tree to print a backup copy and now I need one. IRS has the power to go back a number of years so TurboTax should support printing for at least that many years.
