K-1 (1120S) K-3 with only US source income

I'm using TurboTax Premier for tax year 2021 (download version)

I have a K-1 (1120S) with Part III box 14 checked.

 

TurboTax says 'Enter info from your Schedule K-3'

     Foreign Country or U.S. possession

         I entered (not applicable), then clicked 'Continue'

TurboTax says 'Enter Gross income information'

    It has boxes for:

        Foreign branch category (Column B)

        Foreign Gross income - Passive category (Column C)

        Foreign Gross income - General category (Column D)

        Foreign Gross income - Other category (Column E)

        Foreign Gross income - Gross income sourced at partner level (Column F)

        Foreign Gross income - Gross income from all other sources (Column G)

But, it does not have a box for U.S. source (column A)

 

1st page on my K-3

    E     Check to indicate the parts of Schedule K-3 that apply.

                The only box that is checked is 2

                1 and 3-7 are not checked

 

My K-3 only has values in 1A (Sales US) column A (U.S. source) and column G (Total).

    There are no values entered in Columns B, C, D, E and F.

My K-3 has no values entered in Rows 2-23

My K-3 only has values in 24A (Total gross income) column A (U.S. source) and column G (Total)

My K-3 only has values in 25 (Expense allocable to sales income) column A (U.S. source) and column G (Total)

    There are no values entered in Columns B, C, D, E, and F

My K-3 has no values entered in Rows 26-53

My K-3 only has values in 54 (Total Deductions) column A (U.S. source) and column G (Total)

    There are no values entered in Columns B, C, D, E, and F

My K-3 only has values in 55 (Net income loss) column A (U.S. source) and column G (Total)

    There are no values entered in Columns B, C, D, E, and F

 

Why does TurboTax not ask for the U.S. source income?

 

Is TurboTax not able to deal with this situation (only income from U.S. source)?

 

Was my K-3 filled out incorrectly by the company that sent it to me?

Was Box 14 on K-1 checked by mistake?
