Hello maybe somebody can assist/help me on this topic; 

I completed the tax for my customer a few weeks ago; its a MFJ return claiming the their mother as a dependent. Mother makes under $10k in SS benefits and they supported her throughout 2019. 

Now the received a letter from the IRS requesting form 8962 for the premium tax credit to reconcile the advance credit payment. I assume the mother was  under the Obama health care program. I have their mother's 1095-A form for the mother; how do I enter it in the Health insurance market place? there Is no place for dependents information? 

thank you for you help
