Where to enter Self Employed Health Insurance

Or did you mean Schedule A?
Self-employed health insurance deduction goes on Schedule 1 line 17 (which goes to 1040 line 10), as long as the expense is not greater than your net self-employment income (your net profit on Schedule C reduced by 1/2 of your self-employment tax)
If it does exceed your net self-employment income it gets split automatically. An amount equal to your net self-employment income goes on Schedule 1 and the remainder gets added in to medical expenses on Schedule A. It will not reduce any SE Tax on a net profit. It just reduces your AGI.
