You can change your address with the IRS.

Note that amended returns take 6-9 months or so to process.
Ahah! thank you for the link to the change of address form.
6-9 months...yeah I talked to a friend that does tax returns for part of her job and she indicated the refund from the amended return would be a Christmas present. Seems like that is about accurate at this point.
Hope they process change of address forms quicker than amended returns.
File a change of address with the post office, too. I believe they will forward the check if it gets sent to your old address.
