Repayment of APTC Due to Enrollement in NJ Marketplace Plan and Medicaid Health Plan

In 2021 unknown to me I was enrolled in both a New Jersey marketplace health insurance plan and medicaid. I believe this called enrolled in other qualified heath insurance. This apparently occurred during the transition from Healthcare.gov to the NJ Marketplan (GetcoveredNJ.gov)  even though I had estimated my income above the medicaid income limit.  I did return a form to medicaid July 2021 to terminate the insurance in when I was notified by the NJ Marketplace ,  but medicaid was still not terminated. 

 

NJ retroactively removed subsidy and I have to pay the  full premium to the insurance company for Oct, Nov, and Dec 2021 and is shown on the 1095-a  Will I have to repay additional subsidy to the IRS ?
