Business & farm

I got energy transfer stock too without realize how complicated the tax filings are.  So, if we file separate entries for box 1, 2 and 3, and also for each tiered PTP (3 of them: ET, USAC, SUN), it means 9 total k-1. That is fine but how to enter the sales information? The sales info can't be split.  Anybody can help shed some light here? Thanks!
