Did you look to see if you have a temp file for that tax return? It has the same name as the file you were working on, but starts with a squiggle "~" . It may contain all of your work. IF you find it....open it...and look at it, if it contains most or all of your work, do a Save-As to the desired filename (without the "~" ).

There were some Windows updates done in the past two weeks, if you are using Windows, make sure you install them and reboot.....a partially-installed Windows update has been known to cause TTX operation problems.
