I am self-employed and bought insurance for family members. One of the family members bought insurance on the Obamacare exchange. My self-employed income exceeds the insurance costs. No matter what I do, though, the Obamacare insurance shows up on Schedule A and is NOT reducing my self-employment income. These costs do me no good on Schedule A. I did characterize them as I was previously instructed, but that didn't change anything.
