Since I don't have the 1099R for 2023 this is a guessing game. I have put the full distribution in box 1 and the taxable earnings in 2a.

For the distribution codes, I have changed this so many time. My latest and will be my final answer is 8T. That works - puts it on 4a and 4b, I have waived any penalty. So hopefully this is somewhat correct because I am going to put this return to rest. Done!
