Can I deduct health insurance business closed?

I closed my business 12/31/2018.  Because of the nature of the business I had some income and a few expenses the first quarter of 2019.  Can I deduct my health insurance premiums for any of 2019 as a business expense?  I changed to a self pay plan 6/1/2019.  I am filing a Sch. C - self employed.

Thank You!
