I don't think that the form really affects your health coverage through heathcare.gov. As long as you can prove that you were never offered health coverage you can sign up for health insurance through the marketplace. The only thing you report on your tax return for health coverage is months covered, income, and the form they send you from healthcare.gov (1095-A). From your employers perspective on the 1095C they report that had you been eligible they would have offered health coverage. I really would not worry about forms 1095-C or 1095-B if you do not receive health coverage on them.
