"Where do I report a nondividend distribution that is a return of capital?"
That figure does not get entered anywhere on your income tax return since it is a return of capital from an investment, such as a stock, bond, or a fund.
You would ordinarily keep track of this figure because it will reduce your cost basis when the investment is sold but, in this instance, the trust will (or should) be keeping track of the basis since the trust owns the investment vehicle.
