Medicare premiums are generally entered with your social security income. The SSA 1099 reports your gross benefits, any voluntary Federal taxes withheld, and Medicare premiums withheld from your benefits. If there were Medicare premiums paid that were not reported with your SSA-1099, you would report those premiums has health insurance premiums in the Medical Expense section of the program.
