I filed my taxes & didn’t know I had health insurance until opening mail saying I did have insurance for 2017 but had already submitted my taxes

Depending on what type of health insurance form you received, you may or may not need to file an amended return.

If you have a 1095-A:

If you have a 1095-B, a form titled Health Coverage, the IRS does NOT need any details from this form. You can keep any 1095-B forms you get from your health insurance company or the government agency that sponsors your plan for your records.

If you have a 1095-C, a form titled Employer-Provided Health Insurance Offer and Coverage the IRS does NOT need any details from this form. You can keep any 1095-C forms you get from your employer for your records.

If you have form 1095-A and need to file an amended return, see below. Please note that the IRS recommends waiting until the original return is completely processed (refund received) before filing an amendment.
