When entering two Schedules K-1, each particular item in boxes 1 through 20 is to be entered on only one of the two Schedules K-1. It probably makes sense to put only the box 1 entry on one and everything but the box 1 entry on the other. The reason that it must be split is because the questions that TurboTax asks about the box 1 entry are different than the questions that TurboTax asks about the box 2 entry.
