if you read some of the notes in the cover letter to the K-1 package you may see wording to the effect that the IRS has never clarified how a PTP should report PTPs that it owns. to keep things simple, I just report on 1 k-1. you may appreciate that if you ever dispose of Energy Transfer because the details for the disposal as provided in a sales schedule that will accompany the k-1 are consolidated. so if reported separately you have to do something in TurboTax on those other two Turbotax k-1s to free up their suspended losses. I used 3 k-1s and when I sold. I went back to ET to ask for details for each. never got a reply.
