Do I need to add my partnership's K1 or do I use the "Self-employment income and expenses" option?

In this IRS document https://www.irs.gov/pub/irs-pdf/i1065sk1.pdf I read, "Do not file it with your tax return unless you are specifically required to do so" regarding the K-1. It's on the first page of the document under "General Instructions."

Do I not need to add this K-1 to my return? Do I just use Self-employment income and expenses?
