Well, roughly 2.6 million Americans died in 2014. I've read that 1 in 500 estates gets taxed so that's about 5200 estates.

19 billion / 5200 = an mean of ~3.65 million per taxed estate. That's all I know off the top of my head.

In general I've found the trope of "the rich don't pay taxes because of their fancy lawyers and accountants" generally turns out to be false.
