I don't want to read through all of what the 1095-C entails, but it seems like what it's doing is just certifying that you had health insurance last year right?
Had you received the 1095-C before you filed, would it change anything on your tax return? I don't just mean the final taxes or refund owed, I mean anything on your return. If yes, you should file an amendment to your taxes with Form 1040X.
If no, just file away 1095-C for your records and carry on.
