This is extremely helpful. A follow-up question. My Part B and Part D premiums were deducted from Social Security, so those were entered. I paid the premiums for the Supplemental plan from my checking account. Do I just add the supplemental amount on the line that already reflects the amount withheld from Social Security? I'm asking because the total then would not equal what was reported on SSA-1099. Wondering if that would flag in the IRS system.
