1041 K-1 section 14 Other Information, Line I

My 1041 K-1 line 14 I asks for additional information related to foreign income in the form of 3 questions: 1) Gross income sourced at the Beneficiary level, 2) Gross income sourced at the Beneficiary level, US Source, 3) Gross income sourced at the Beneficiary level, Foreign Source.

All the information comes from my 1099 and the countries are RIC. I can figure out the gross of the foreign source but not sure what the beneficiary level and beneficiary level, US source means.

Any thoughts?

 

Thanks
