I'm not a tax expert, just a layperson, but my understanding is 1095C does not need to be filed with taxes. Keep it for your records - it shows the type of health insurance coverage you had for ACA requirements. 1095A is what you get when you are actually enrolled in a subsidized ACA plan through a state or federal (healthcare.gov) exchange. That's the one that you need to report on taxes. If you applied and were rejected, you would not have a 1095A. The two are different forms for differerent purposes.
