I waited for the IRS letter in the mail before I faxed mine. The letter instructed to include a cover page showing who to send it to, Control Batch Number etc., a completed Form 8962, 1095A, and the actual IRS letter you received in the mail. I waited 22 days before calling to confirm if they receive it or not. The IRS agent was able to locate mine right away. So, I'm not sure if including the IRS letter with the fax probably got my return to process faster. Hope you'll hear something soon. Good Luck!
