late backdoor Roth for 2023 and 2024

my wife made late backdoor Roth contribution in 2024 for both years of 2023 and 2024. 

we did not report it in 2024's tax return.

now I received 1099-R which just shows the total amount of contributions for both years. 

I am using Turbotax desktop version, cannot figure out how to report this.

really need help, thanks!
