Resending a refund check can take a while especially since you had to put in a change of address ... I would watch the IRS Where's My Refund tool for a new date of mailing over the next 6 weeks.
Here is the way to contact the IRS if you don't see the check in 6 weeks ....
Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday
When calling the IRS do NOT choose the first option re: "Refund", or it will send you to an automated phone line.
So after first choosing your language, then do NOT choose Option 1 (refund info). Choose option 2 for "personal income tax" instead.
Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions." It should then transfer you to an agent, but there is likely to be a long wait.
