Experiencing the same problem, I have kept TT up to date, the last update according to the history tab was 2/9/2020, now at 2/10/2020 I cannot file. I have already filed one tax return before this update and it worked fine. Could it be the software writer forgot to put in the new version number in the code, therefore it does not match with current version number and thus returns a false therefore this endless loop has started. Hope it gets fix quickly.
