Energy transfer partners k1

I have a couple of questions about the Energy Transfer Partners K-1. I notice they list 3 companies in the supplemental material and was wondering if you have to enter 3 K-1's into TurboTax or if you can consolidate the data in one K-1. Also if you have to use 3 K-1's can you use the ETP address for all 3. Also line 20 on the K-1 there is a code "Z" and when I enter this TurboTax asks for additional information none of which seems to match what is on the ETP supplemental form. Any help would be appreciated.
