After 21 days, you can phone the IRS to see if you can learn what the delay is.
IRS: 800-829-1040 hours 7 AM - 7 PM local time Mon-Fri
When calling the IRS do not choose the first choice re: "Refund", or it will send you to an automated phone line.
First choose your language.
Then press 2 for "personal income tax".
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.
I usually use a speakerphone so I can work on something else while waiting.
