I filed 1/29 and my return is still processing. It contained both a 1099-R and W-2. Used standard deduction. On 3/11 I got a letter saying it is under review and I may need to wait 60 more days. No further explanation available. I usually file in late March with no problems.
EDIT: Found this on the web. Note the late deadline for electronic 1099-R, much later than the paper we get.
The filing due date for Forms 1099-R is February 28, 2024, if filed by paper, and March 31, 2024, if filed electronically. 1099-R copies are due to recipients by January 31, 2024.
