Form 1095-A issue

At the end of 2021 while signing up for the ACA, my 22 year old son was in college full time.  The assumption for 2022 was that he would remain a full time student.  Therefore, his ACA insurance was priced as if he were a dependent and part of our tax household.  I estimated his earnings and received PTC accordingly.

 

However, in 2022 he did not attend full time and less than half time.  He also worked and earned almost 6K.  When I did taxes using turbotax Deluxe, the program stated that he did not qualify as a dependent.  I received three form 1095-A's since both my wife and I turned 65 and had to drop ACA coverage in March and June. 

 

I completed our federal/state taxes and entered all three 1095-As.  Returns were accepted.

 

Since he now had to file as 'single', we did his taxes and they were rejected, stating "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."

When went back to his tax on turbotax, I see that I did not go thru the section asking for a 1095-A.  I went thru it and it prompts if he received a 1095-A and I answered 'No'.  Will this go thru now?  Or must I somehow go back to the ACA and do who know what?  Thanks for your help!
