Inherited large trust with US Bank... how can I make sure I'm not getting screwed?

Inherited a large trust (8 figures) from my uncle.

It has been a couple years and everything is settled. I have never been happy with the transparency of my trustee (also US Bank). It has been very hands off in my end - basically I just get the money deposited 4x a year.

In the will it states that I can change my trustee at any time. I'm not getting the payouts that I think I should be getting- they seem small compared to the size of the trust. And I also haven't seen the trust grow much either (but I am not very financially savvy- so what do I know?).

So who can I go to make sure I am getting the best deal? A CPA? A lawyer?
I'm just at a loss as to how to proceed. I know I am NOT happy with US Bank, but if it is the best place to keep my money I will. But I just have this feeling that I (and my kids someday!) will be better off to get out of there!

Also should the trustee also be in charge of the money management? Seems like a conflict of interest to me.

Just in case it matters, the trust is held and created in Florida and I am located in Wisconsin.

And last year my payout was around 2%.
