If you already received the third stimulus check you qualified for, look for a letter in the mail from the IRS confirming your payment. Since March, 164 million payments have been sent out on a weekly basis by the IRS through direct deposit or by mail. If you think you got the wrong payment amount (check your amount here) or you still haven’t received your payment, keep the IRS letter when it arrives. What is taking the IRS so long to process my tax return? Because of the pandemic, the IRS ran at limited capacity last year, which put a strain on its ability to process tax returns and send out stimulus checks.

The IRS is now open again and processing mail, tax returns, payments, refunds and correspondence, the agency said, but the pandemic continues to cause delays in some of services. If you believe you received the wrong amount — such as if a dependent was skipped — or the total doesn’t match the estimated amount from our stimulus calculator, it could indicate that you may need to hunt down your missing money using this letter. The IRS advises you to hold on to the letter for your 2021 tax records.

Also, make sure it’s been at least 24 hours before you try tracking your refund.
