What does the NJ state return mean when it asks if this is the first withdrawal from this IRA, and then for the Value of all IRA's on 12/31/2020?

My wife is forced to take a Required Minimum Distribution (RMD) from an IRA she inherited from her great grandmother (?). Why does NJ care what the value of "all IRA's" are? What does this even mean, exactly? The value of all IRAs in my wife's name? In either of our names? 

This is keeping me from submitting, and now I have missed the 10/15 midnight deadline ...
