Parents have 1095A.  The son who is 27 yrs old was listed on a separate 1095A where the recipients name is the parents. I filed that form under the parents tax return.

The son's tax return rejected by Taxing Authority.  Error F8962-070: The e-file database indicates that Form 8962 or a binary attachment with description containing "ACA Explanation" must be present in the return.  This return rejected due to Form 8962 Premium Tax Credit missing from the return. In order to complete Form 8962, he should have Form 1095-A Health Insurance Marketplace Statement with relevant information on the insurance that he purchased in the marketplace.

He did not purchase it. The parents did not purchase it. What do you do?
