How do I report K-1 for a stock with royalties?

I have shares of a stock called Sandridge Permian Trust (PER).  It is a "statutory trust, which engages in acquiring and holding royalty interests in specified oil and natural gas properties."  Every year I get  K-1 from this company which is confusing to report on my taxes.    The K-1 has entries under Interest Income (box 5),  Royalties (7), Deductions - Royalty Income, Deductions - Other (box 13), Tax-exempt interest income (box 19), Investment Income, Investment expenses, and Interest expense for corporate partners (box 20).  The stock is a PTP.  I am a Domestic Partner, and a Limited Partner or other LLC member.  How do I report these values for my 2020 tax return and which extra forms will I need to file?
