Received lump sum distribution from 457 account after changing employers. Did not get a 1099-R, only a W-2 for the 457. How to file?

I changed jobs midway through 2023. My old employer had a nongovernmental 457b plan which I was contributing to. My new employer does not have this and so I was required to take a lump-sum distribution from the 457B plan. I received only a W-2 form for these distributions and did not get a 1099-R. My question is, is this correct, and would I need to pay any penalties for the early distribution from my 457b from when I changed jobs?
