Inherited IRA non-qualified beneficiary RMD question

I received an inherited IRA in Feb 2024 from the estate for my cousin, David.  David passed away at the age of 73 in July of 2023.

 

According to TurboTax Deluxe 2024, screenshot below, David should have made an RMD withdrawal in 2024, after he was already dead. The "withdrawal" was made by me, after I inherited the IRA. This withdrawal closed the inherited IRA account, so I selected No.

Do I need to talk to the executor of the estate to see if they took out an RMD when filing David's 2023 taxes?

If they didn't, are all of the non-qualified beneficiaries liable for paying the 2023 RMD? There were several of us.
