I have a client that has set up an LLC for either flipping or buying properties to rent. The business is a partner in another business.  He received a K-1 naming his LLC as the partner using the EIN.  How do you link this to a schedule C.  Everything I'm reading on IRS website states that only an individual can be a partner.  But, if this is the case, why under Information about the partner is there a section that says if the partner is a disregarded entity, enter the partner's TIN and Name.  I really feel like I am missing something so simple.  I guess my brain is fried - I am really struggling with this one.  Thank you.
