Your question is not very clear: Is taxpayer receiving SSA retirement benefits in 2021? Is the Medicare B & D deducted from his SSA? Or, is he paying it himself by check or bank account ach? Did he pay supplemental health insurance premiums during 2021? Did he pay accident, heart, cancer, etc insurance premiums during 2021? Did taxpayer receive a refund back from a health insurer for health insurance premiums that he paid previously during 2020 and/or 2021?

Did you report any health insurance premiums that he paid on the 2021 Schedule A?
