What does "gross income sourced at beneficiary level" mean when TT is asking for details about foreign income reported in box 14 of a trust k-1?

I am using a 2018 Premier Turbotax CD for a Mac.  A trust k-1 reported foreign income (and tax payments) distributed to me with respect to dividends payed to the trust by the ADR of a foreign corporation and by mutual funds that owned foreign companies.  

I don't understand the term "sourced at beneficiary level" in that context.  All of it was sourced at the trust and then distributed to the beneficiaries.

Does it want all to know about all income disbursed to me on the k-1, and then a breakdown of US versus Foreign income?
