Never received amended refund

[lasaersr]

I received the CP21B letter regarding my amended 2024 return. It states I would receive my refund within two to three weeks from the date of the letter if I hadn't already received it.  It is now May 23 and I have not received the refund check.  That is 11 days after the time frame given.  Should I give it more time or file form 3911 (Taxpayer Statement Regarding Refund)?

Please see this link from the IRS that has an explanation for reasons for the delay. There should be a number listed on your CB21B notice in the section titled "What you need to know" that you can use to call the IRS for an updated status of your return.

Also, if you are still having issues after contacting the IRS, you can follow the steps to contact a Taxpayer Advocate in the link provided.  A Taxpayer Advocate will act as a liaison between you and the IRS if you are unsuccessful in obtaining answers when contacting the IRS directly.
