This is explantion given my broker:
What you are seeing on the 1099-b are Principal Payments that were paid by the trust. The principal payments are not credited to the account but are dollar amounts that were allocated directly by the company to reduce the basis in the position and offset the investment expenses listed on the Nonreportable Transactions section.
In essence, the trust is selling the underlying commodity (principal payments on the 1099-B) to cover the expenses for operating the trust (investment expenses on the Nonreportable Transactions section).
My question is how and where do I enter on form 8949 when step questions do not give info.
