Here is how I fixed it...In my case, it was a child's SS number that I claim that was covered by the exhusband on ACA.
My ex carries medical insurance through the ACA for BOTH kids. Sooo, my return kept getting kicked back with e-file reject F8962-070. I figured out that I had to answer 'yes' to did you receive a 1095 A (even though I did not - but, the child I claim is covered by the 1095A), then open the forms section and filled in the 1095A (because the TT program will NOT walk you through this) and filled in the recipient as the ex, then the insured as our child that I claim. Then , I did have his 1095A so I filled in the columns correctly from that form ...and THEN below the columns of months (line 33) there is a small section "Shared Policy Allocation Information Smart Worksheet" in a box that asks how much of the PTC I am splitting with the other person. I put zero 0 in these sections and my ex's social security. Once you put zero 0 in the "Shared Policy Allocation" section you will see your refund amount go back to what it was before you put in the 1095A. This seemed to work as my return was finally accepted after 4 fails and not finding any help on this site or others.
You can solve this by using the "shared policy allocation information smart worksheet" in Turbo Tax by switching to "forms" and opening it manually. Turbo Tax will not prompt you for this problem.
