Thanks--I think the problem stems from the 1095-A showing that I took a PTC in column C. This further stems from initial sign-up to the insurance plan. I should not have received any credits at all, and should have had zero discounts. Clearing form 1095-A in Turbotax just re-creates the same results again, as my form does indeed show discounts, but it turns out I should not have had them and it took some time to correct with my insurance provider.
