Actually per IRS guidelines the deduction goes on 1040:
"Line 14
Deduct contributions to employee benefit programs. Do not include on line 14 any contributions you made on your behalf as a self-employed person to an accident and health plan. However, you may be able
to deduct on Schedule 1 (Form 1040), line 29, or Form 1040NR, line 29, the amount you paid for health insurance on behalf of yourself, your spouse, and dependents, even if you do not itemize your deductions."
