What do I report for an LP in a Roth IRA?

I purchased 20 shares of a Energy Transfer LP in my Roth IRA through Etrade.  At the time I did not know anything about LPs. I sold it last year as I learned more about LPs. I received a K1.  It did not make any money.  There are about 30 states listed, but all report zero in the far right column for reporting state tax, thankfully.  What do I need to report on my tax return for this year?   What form would I complete?
