I have tried all the suggestions that have been given in this entire post and nothing fixes the problem with opening my almost complete tax return. My issue is at the same as others have noted, I could access the file for a few days after starting, then when I was ready to finish my taxes, Turbo tax performed an update and I could no longer access my file instead getting the dreaded message referred to in this post.
I find it interesting that the TT "experts" don't really provide any help, but instead they seem to be glad someone else figures out some way to fix some problems and want a thumbs up for someone else's recommendation.
From my experience and others as noted in this post, the problem happens after a TT update, which can not be controlled. The turbo tax experts have never acknowledged this as a problem and no fixes have been forth coming, as this has been an issue for at least 2 years.
Extremely frustrated with TurboTax and dreading having to start a new file and have the same issue after a random update.
