If the website can’t find your tax refund, it will ask you for more information (such as the approximate date you sent in your tax return). If the "Where's My Refund" system still can’t find your form, it will provide a phone number for you to call.
You can try calling the WMR automated hotline instead: 1-800-829-1954
