Can I give you one more example, please?       My client (married - both over 65 - receiving medicare)  has a house cleaning business.  They have a medicare supplement.  Can she deduct her supplement premium as well as Medicare premium on the 1040 as self-employed health insurance?  If so, she can't deduct any part of her husband's premiums, can she, since he does not share in the business?

Thanks for your patience.
