Is it correct to enter amounts deducted soc sec for medicare parts B,C,D as insurance expense on my schedule C? Or will this be counted twice?

[MichaelMc · Accepted solution]

Yes, if you are self-employed and eligible for the self-employed health insurance deduction, you can include your Medicare premiums in your self-employed health insurance deduction. It's a deduction on the front page of the 1040, line 29.  

If you want these premiums to be part of the self-employed health insurance deduction, do not enter your Medicare premiums when entering the information from your SSA-1099 (Social Security Benefits). When you go through the questions for your business expenses, enter those premium expenses for self-employed health insurance premiums.
