After you file

Sorry, but you can't expect TTX to store your files for free for years.

 

If you download your tax returns as a PDF file EVERY YEAR, right after you file has been accepted, then you never have to worry about it.   They are always available in the year you file..up until mid-October.   Then Back-Them-Up off computer too. (Hundreds of people have computers crash with no backup every year...then what?)
