To enter the insurance premiums, you will do as follows
If the business is a partnership or an S-Corp, you will enter the self-employed health insurance at the end of the K-1 entry section.
If you are self-employed, you are allowed a deduction for premiums that you pay for medical, dental and qualifying long-term care insurance coverage for yourself, your spouse and your dependents.
You can only claim the health insurance premiums write-off for months when neither you nor your spouse were eligible to participate in an employer-subsidized health plan.
