Deductions & credits

Thank you for your reply. Would having another insurance policy (i.e. my marketplace coverage) for the entire duration of my employment mean that I had disqualifying coverage? If this is the case, do I mark that I did not have HDHP coverage for any month on form 8889-T? I read online that I should contact my benefits provider to have them reclaim the HSA payment made by my employer--would you agree this is the correct thing to do in this case?
