there are two types of non-covered securities. One where neither cost nor tax basis is reported to the IRS and the other where proceeds but not cost is reported. the first type would be categoty/class C or F. the second would be category/class B or E. unsure? ask the issuer.
B & C are for short-term and E & F are for long-term
in any event that 1099-B was sent to the IRS so you need to report it on your tax return
