I tried these suggestions without success. I always clear my computer history
after every session, so there was nothing extra to do her. I tried a different web
browser, Chrome instead of Safari ... same message. I copied and renamed
the tax file ... same message. I could open other tax files, but never this one.
I finally got in touch with Turbotax Help, who told me that I would have to
start over and re-enter everything in a new file. There is basically no back up file
in Turbotax to the live one on which you are working.
