Problem with Turbotax software

I was working on a 2016 return in TurboTax and had nearly completed the Federal portion, and saved it.  When I went to reopen the return to continue, I saw a brief flash to say that TurboTax had encountered a problem and could not open the file.  There appeared to be a box to recover the lost work, but this did not seem to work.  Now I can only return to a blank return.  Is there any way of recovering the lost effort?
