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.
