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?
Though you seem to be able to get in:
If you are using a Windows device...a few users have had partially installed Windows updates waiting for a reboot (two were issued this week) and that was blocking the full operation of the tax software. Try a full computer re-boot and then see what happens.
IF it's a MAC, then we might have to get one of the MAC people involved.
