What is a 1095-a?

[Marketstar]

If you bought health insurance through one of the Health Care Exchanges, also known as Marketplaces, you will receive a Form 1095-A which provides information about your insurance policy, your premiums (the cost you pay for insurance) and the people in your household covered by the policy.

I didn't buy insurance from any in this group.  What do I do when asked about it?
