I'm using TurboTax online (Chrome browser on Windows 10), and I was able to e-file my return with form 7206 successfully this morning.
The forms-not-complete message still showed when I went to the Review section today, but there were no longer any forms line listed under that message (7206 had been listed, as recently as yesterday). I was able to click "Continue," complete the review and e-file.
I wonder if some who are unable to e-file may have issues beyond form 7206 that need resolving as well.
