My Schedule K-1 Box 13 has nine line items grouped under Code-T, two of which are Interest Expense and Charitable Contributions. The K-1 is for Calumet Specialty Partners, LP (CLMT). They are in the oil and gas refining business and have lots of debt so I'm guessing that the Interest Expense is for loans. Maybe the Interest Expense should be under Code-H and not Code-T??
