I had the same issue as a CD user on a PC and finally was able to eFile both Federal and State at the same time AFTER I manually updated my 2019 deluxe product. Follow this link and click on step #2 to update to the latest and greatest version:

I have no idea why the regular update process isn't working, and honestly why many of the turbotax employees give bad responses in this forum, but appreciate the few of them who are apologetic about this. It seems though there should be a better way to let thousands of customers know that a problem exists and when we can expect real help to get our taxes done.
