Were the kids insured by the parent at the same time as they were covered by the Marketplace insurance?  If so, where was the insurance through the parent's from (employer, Marketplace, something else, etc.)?  That can affect the SLCSP.

Because the kids and the aunt/uncle were all covered on the same 1095-A, the amounts will be "allocated" between the parents' return and the aunt/uncle's return.  IF they can agree, they can choose what percentage to allocate to each return.  Are they agreeable to allocating it for best overall result?  Or are they going to allocate things based on the number of 'covered' people on the 1095-A?
