RMD

My 401K plan had one administrator for 5 months and a different administrator for 7 months.

 I received two 1099-R. The RMD amount for the first 1099-R does not meet the total RMD required for 2023. The second 1099-R  well exceeds the RMD requirement for 2023. How do I report the RMD On the tax form.

 Should the required RMD be split 5/12 of the total due for one 1099-r and 7/12 for the other 1099-R.

  Should I claim zero on the first 1099-R  and the total RMD on the second 1099-R.

              Thank you for a reply
