schedule K-1, box 16 is checked (k-3)

My schedule K-1, box 16 is checked (k-3)

my attached K-3 only lists a single entity (US) as the foreign country or US possession.

the foreign country or US possession; US possession IS NOT AVAILABLE on TURBO TAX

So, on my schedule K3, part 2, line 24 and it shows total gross income US $1797.

But on the turbo tax it shows Foreign gross income $1797

does TurboTax plan to add the US to the list and handle those inputs?

OR SHOULD I UNCHECK BOX 16 ON K1? please advice
