For what its worth, I had the same problem. Going back to the step-by-step section to review the 1095A was useless as all the answers to the questions asked were correct and the final check said everything was fine and ready to file. I did open the 1095A form directly and found there were a few items not filled in and one social security number that was listed under the wrong name. I filled in everything directly in the form from my insurers 1095A and re-filed it and it was finally accepted. Hope this helps.
