Ah, Flash, I think that it cannopt be taken directly off the Schedule C, but must go through the "health insurance for self-employed" loop, just as if you were buying insurance on the open market. Add it to the premiums that you pay personally for Medigap and Part D (drugs), and plug that sum into the SE health insurance box on the 1040, add water, carrots, and onions, and follow the directions to get soup, I think.
BTW, I do not think it makes any difference how you pay the basic Medicare premium; if you have it deducted it's just as if an employer deducted your share of your health insurance costs. BUT, I would check.
