Actually, I did all of the steps that you suggest below.
I started by first updating the software, then did the file save step as I proceeded with entry.
AGI: I filed early April '20, and entered the correct info.
So, I did my research, but still had error messages and issues with sending files.
If I got bad info, then folks who are less adept at this software should avoid using the desktop version AT ALL COSTS.
Not worth the hassle; will use TT online next year to avoid this mess.
