Business & farm

Hi. Sorry if this is not a related matter. I automatically uploaded all the information from my broker (Robinhood) but later on I received a Schedule K-1 Supplemental Information Statement from one of the stocks I own (EPD). is That information for verification purposes only or this is something that needs to be included manually? I am guessing that all the information regarding dividends, interest, etc., is included on the information sent by the broker, but just wanted to be sure before filing.
