It's not the settings. One example, I have a trust that owed $4600 dollars for 2020 and overpaid by $8000 with last year's estimates. With option 1, this return is applying $341 to 2021 tax and calculating estimates that total $1023 and refunding $8000. With option 4, it applies $1,364 to 2021 and then refunds the $7000 balance. All of my fiduciary returns that require CO estimates are doing this.

I just called Lacerte and they want to waste my time with a calculation challenge rather than take the return and review it themselves to figure out what is wrong then fix it.
