Retirement tax questions

Hi, Thanks for posting this question, as I have exactly the same issue but for 2024/2025 since I turned 73 this year.  I understand I can split, and that I need to complete the 1st 2024 RMD by early April 2025 and also take a full 2025 RMD . 

What I still find confusing is how to list the split RMD in TurboTax/on Fed tax forms.  I think TT/the tax form asks what the full initial RMD amount is - say it's 10k, but my 2024 distribution is only 8k, with a plan for the remainder 2k in January.   Is there something I need to do to clarify what I'm doing or do I just fill in the 8k and assume it gets sorted out in the following year taxes?   Visions of IRS and penalties......
