I received a 12C letter from the IRS, because I didn't file my 1095-A and Form 8962. I amended my return and have those forms; the IRS explicitly requested just the completed 8962 and a copy of the 1095-A, and actually said not to send a 1040X or whole Amended return. However, I also received a 1099-SA in the mail so I put that in the amended return. Do I need to send the form 8889 from this just in case, or since they did not request this, will this cause problems? I did not go over contribution limits, and the distributions were for health care only.
In response to the 12C letter, do as they say and only return the 1095-A and Form 8962. I can almost guarantee there will be confusion if you send in an amended return that also includes more information.
In regards to the 1099-SA, I would be inclined to keep the record and not amend. If you receive additional notice from the IRS later this year, you could then address the matter. The 1099-SA will not affect any refund processing and can be quickly resolved with a response to a letter should you get an inquiry.
