Is the box 2b total distribution on the 1099-R checked?

It is on one of the 1099-Rs

I inherited several different IRAs. Only one of the 1099-Rs had the total distribution box checked.

RMDs start in the year following the year of Death.
If you don't have an account anywhere with your name as beneficiary, then the IRAs were liquidated.
Just answer YES.

you should have gotten something from the executor explaining all this.
An inherited IRA does not have to be liquidated, that should be your choice.

Unfortunately, that was not explained to me.

IRA's that have a named benificuary do not pass through the estate.  They go directly from the financial institution that is the custodian of the account to the benificuary.   The estate executor  would not necessarily have any knowledge of the account or responsibility.  Only if there was no named benificuary or the estate itself was the benificuary would the estate be involved, but in that case the estates beneficiaries receive a K-1 from the estate, not a 1099-R.

I was confused and perhaps misread the poster's phrase " inherited an IRA". I guess this was not an Inherited IRA. I still don't understand why the poster got a 1099-R.

If it is an inherited IRA then the box 7 code on the 1099-R would be a 4.
