The letter specifically said to NOT send 1040X. If I was expecting money back on my original return and now after amending my taxes it shows that I owe, how do I know how much to pay? Do I pay the amount on my 1040X even though it specifically said not to file a 1040X? Do I pay the amount that I owe on my 8962 minus my previously calculated refund on my original 1040?
