Did you file your 2007 tax return and request the refund check to be directly deposited to your account or mail the check?
If you chose the option to get the check mailed than yes, the check would be forwarded to your Missouri address if you have requested all your mails to be forwarded to the Missouri address.
Let me know if you have any question.
