What if I had a HDHP in all of 2019, but no HDHP in 2020?

We had a HDHP in 2019. We switched to a Healthshare in 2020. Turbotax is asking: "What type of health coverage did you have on December 1, 2019?" I marked "Family" as our HDHP coverage ended 12/31/2019. But we did NOT have a HDHP in 2020, and do not have a 1095 form or a 8889-T form.  When I "smart check" my return I get an error for blank entries on a 8889-T form. Any idea how to fix this?
