I have checked the box "No marketplace insurance purchased" in the Credits section. I have filled out under General/Electronic Filing/Efile PDF Miscellaneous and gone to efile attachment. I have uploaded a pdf document titled ACA Explanation with the explanation that my client has company provided insurance and has never had marketplace insurance. And I marked the box send the attachment with federal return. It has rejected 3 times when I tried to efile. When I check the return, the critical error is still there, even after refreshing, and says there is a problem loading the input screen. What am I missing!!!!?
