The K-1 tax form is sent directly by the partnership, and is not a Fidelity tax form. If you have questions about your LP K-1, you must contact the general partner or the partnership. If you believe your retirement MLP K-1 is inaccurate, contact Fidelity. Fidelity cannot review nonretirement account MLP K-1s. You need to contact the firm that services the partnership. Nearly all MLPs are serviced by either PricewaterhouseCoopers or Deloitte.
