Form 1095-c Received after taxes were filed. What do I do?

Hi, I have never heard of this form before so I filed my taxes as soon as I got my w-2 like I always do. Today I received this form in the mail, but I have already filed and gotten my refund already. Is this bad?  I seriously had never heard of this form before today. I did check off that I had health insurance when going through the turbo tax system but it didn't mention this form.
