Yes, for the state you are required to have health insurance. If you did not you either have to file for an exemption or pay the penalty. Unfortunately, there is nothing you can do about it.
Massachusetts law requires you to have health insurance.
To avoid a state tax penalty, adults 18 or older must have what the Massachusetts considers "minimum creditable coverage (MCC)" or prove eligibility for an exemption. The rule applies even if you are not required to pay state taxes.
