Do you mean against 1099NEC self employment income? Is the health ins now under your name and separate from your spouse's plan?
Self-employed health insurance policies must be in the name of the business. Sole proprietor can meet this requirement if the policy is in their name. COBRA policies are in the name of the former employer and do not qualify for the self-employment health insurance deduction. Medicare plan B payments are qualified as Self-employed medical insurance premiums and should be entered here instead of in the Social Security Benefits section. If you or your spouse could participate (even if you declined coverage) in an employer's health plan at any time during a given month, you cannot take the deduction for that month. However, payments for those months are deductible on Schedule A if you itemize deductions.
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. 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.
