You filed on Dec 31, 2023? That was way too early. Did you mail it? Efile didn't even open until Jan 29 this year. Did you even have the SSA-1099 and 1099R to enter? Those don't come out until late January. And there were lots of program updates. Next year don't file so early. When I filed at the end of February I got both refunds within 1 week.
