the deduction is not allowed for any month that the self-employed individual is eligible to participate in any subsidized health plan maintained by any employer of the taxpayer or spouse.
two key phrases for which you will have to find the answer. could your husband cover you through his employer (not all employers have spousal coverage) and is the employer's plan subsidized (meaning that the employer covers part of the cost). if the answer to both is yea you don't qualify for the S-E health deduction. if the answer to either is no, you qualify but it is not a schedule C deduction. SE health insurance deduction (enter through schedule c questions) goes on schedule 1 line 16
if you qualify you can not only deduct your medicare premiums as S-E health insurance but also your spouse's medicare premiums per CCA 201228037 and IRC 162(l)
from the CCA If all the requirements of section 162(l) are satisfied, Medicare premiums may (also) be deducted
under section 162(l) for coverage of the self-employed individual's spouse
