Fill Out 1099R for a QDRO 401k withdrawl

I have a QDRO 401k I took money out of in 2018. I did pay the federal tax on it at the time of the withdrawal. So Box 4 is the tax amount I already paid, and the Distribution Code is 2 since the QDRO is exempt from the early withdrawal penalty. Should Box 1 and Box 2a be the same amount? If I took out $10k plus $5k for federal tax should both boxes be $15k total? And should I be putting anything in the other boxes?
