RMD entries

My father passed away in March 2025. Prior to his death, he received $500 in Thrift Savings Plan distributions. After his death, my siblings and I received equal shares of his account balance in lump sum payments, as we were his listed beneficiaries.

 

I cannot find any information about required minimum distributions (RMD) on my 1099-R or his.  

 

For his taxes, Turbo Tax is asking for the total amount of RMD for year ending 2025. 

Then it asks how much of the distribution was applied to 2025's RMD. 

 

Since my siblings and I all have to report our distributions (which will likely far exceed the calculated RMD), can we just list $0 on his total RMD on Turbo Tax,  indicate none of the distribution applied to the 2025 RMD, and report the RMD on ours?

 

I'm probably overcomplicating this, but I'm still very confused and don't want to calculate incorrectly. 

 

Thank you.
