Thanks for the response. It is not clear to me though if column F qualifies as foreign or not? my K-3 has all columns B, C, D and E empty on every row. The only columns that have little info are column A and column F (sourced by partner). IS column F considered like foreign? Only little info in the K-3 that has data is line 49 column A and F, and line 54 and 55 (just because line 49 has data as line 54 and 55 are totals). Nothing at all in columns B, C, D and E.
