Not knowing when you filed, you should have gotten a letter from IRS requesting the form and you have to do the 8962 yourself. They give you a fax number and tell you what to fax like all forms and the letter. My 8962 showed that I got a slight increase in my return because my AGI was a little lower than when I signed up for the ACA. I sent my 1040a to show that but they did not add the amount to my refund. Oh well, it took about 3 months after that but I faxed it in end of Feb. The letter states to NOT send or do a 1040X as it will complicate things they say. Good luck.
