Does anyone know why the IRS changed my ddd? It says reference number 1121

[cerv3030]

I was scheduled for a ddd for 2/22 and didn't get anything that day or on the 2/23. The wmr updated saying that "there was a delay processing your tax return and your expected refund date May have changed. Anyone know what this could be ? It's the weekend so my head is spinning with questions. Should I be worried?

Reference number 1121 is a general code for the IRS. It can be anything.

One of the most common reasons we have seen for returns to be delayed is the AGI is rejected. The IRS will not process your e-file unless the 2016 AGI is correctly reported.
