Deductions & credits

Yes , as long as there is a net profit for your business. 

The following information is an excerpt from the TurboTax help content and it explains this topic in more detail:

Health Insurance Coverage

You can deduct up to 100% of health insurance premiums for you, your spouse and your dependents if you are self-employed and have a net profit from the business for which you created the plan.

Include health insurance premiums you made for your dependents who were under age 27 at the end of 2016.

Medicare B and Medicare D premiums should be entered here instead of in the Social Security Benefits section.
