First time dealing with MLPs. Turbotax software is very lacking in the selling of theses units, Taxact is even more confusing. I had TRGP-PRA which called their preferred shares so they can completely move to 1099s thankfully. The only numbers I got to work with are contributions, withdrawals, and box 19. No sales schedule. Turbotax is mute on the subject and google only tells you what an MLP is no one seems to have an answer on how to do this correctly and not doubled entered/taxed. My broker reports this call on the1099-B as well. The only help I seem to have found was @nexchap thread on entering sales.
