For any month that both spouses are HSA-eligible individuals and one of the spouses has family HDHP coverage, both spouses are treated as having family HSA coverage. Since both of you were HSA-eligible for the entire year, indicate to TurboTax that each of you had family HDHP coverage the entire year.
Also be sure that you have allocated the HSA contributions and W-2s to the correct spouses. The result that you got from TurboTax might be because you did not report yourself as having family coverage or reported the $3,550 contribution as your spouse's contribution.
