If a Sch F is similar to a Sch C, and if my memory is not too fried tonight, a self-employed person can provide health insurance to his employee/spouse for the employee's whole family. It's deductible to the SE taxpayer, I think on Sch F, because it's for the employee. The SE taxpayer's own Medicare premiums are deductible as SE health insurance on Sch 1 line 17, income allowing, with any excess to Sch A line 1.
But, don't trust me on the above! Two more complex returns to get done, and not much sleep last night, or for the last week or more or...! So, research more yourself or wait for someone to jump in with cites for you to rely on.
