So if your K-1 has 3 entities that make up the numbers in box 20 (owns three other partnerships) and each one of this reported separately on Statement A, you would wind up with a total of 4 K-1's with the name of the original K-1 partner and three that contain the QBI information with the EIN's of those three partnership and the associated QBI information. That's my understanding but just want to clarify.
