Well 1800 would be the amount for both for Single. Did you file? The IRS will adjust it if they sent you the second one and first one. You do not need to amend. So you already know they are going to take off the second 600. How much was the total refund suppose to be? Was it more than 1800? Will you still have a refund if they take off the full 1800? Hope you don't end up owing.
