Retirement tax questions

Also pl. clarify how do I use TurboTax 2022 premium when I file 2022 return 

- to report the screwed up IRA (mix of pre and post tax money) that I partially converted to ROTH in 2022

- I am assuming that I will get a 1099R with some code letter and just enter those details

- And pay the taxes on the tax able proportion of the converted money? Hopefully 1099-R will give this figure

 

Is this correct?

 

If correct, what code letter would be for 1099R for this conversion?
