2023 RMD missed in deceased's year of death (2023). Now what?

She passed in August 2023 at the age of 93.  I know the rules have changed in the last few years and don't want to make a mistake.

 

I  found this in Publication 590-B... "If the owner died on or after the required beginning date, the IRA beneficiaries are responsible for figuring and distributing the owner's required minimum distribution in the year of death."  So I assume there are no penalties?

 

I made the beneficiaries aware (once I found out in January 2024) and believe they need to make RMDs for 2023 as a beneficiary by 4/15/24... but can't find the source for this information (I read it somewhere).  Does this sound correct?

 

Turbotax asked about info for form 5329 (part IX) that I provided (I explained what happened, that 96% of the RMDs were taken and that the beneficiaries were informed they need to take RMDs).

 

Do I need to do something else?

 

Thanks in advance!!
