Same issue!  Client does not have Marketplace insurance.  Started working with him in 2016.  He has never had a 1095-A.  A couple years he had 1095-B.  

THis must be a bug in the system!  I thought maybe if I entered the form and just showed no insurance it might help.

Thoughts suggestions?  It's 4/20 just tried to file again still no luck - is Intuit working on a fix for this?
