After you file

Ok ... hate to tell you this but the notice did NOT tell you to amend the return ... it tells you to complete the form 8962 & mail it and the 1095-A to the address provided.  So you now have an amended return that will take as long as 6 months to process IF they even allow it to process since they  have closed the original return and sent the refund.   Nothing you can do but wait until the IRS decides what they will do with the information you mailed in.
