After you enter the K-1 reporting the box 1 income, choose the option to enter another K-1. On the second K-1 only enter the income reported in box 2, not any other amounts that you reported on the first K-1 entry. In other words, do not duplicate any numerical entries. Also, if other numerical entries on the schedule are applicable to the box 2 income, only enter those on the second K-1 entry.
