The "fix" that came from Turbo Tax was a joke. What I ended up doing was to shut down my pc each night and try again the next day. On the third day, when I accessed TT, I finally got a message that there was an update. I clicked on the link to get the update, went into my return and was brought to the File section and was able to go through the last few screens. Be sure to update the date on the signature screens. The Transmit button finally worked.
