Remember that WMI Liquidation Trust is a Trust and not a Mutual Fund or Stock in which you are likely more accustomed to investing.
First, the amount was likely small unless you held a really significant amount of WAHUQ's prior to bankruptcy finalization. The amount of income reported on your K-1 is the interest that accrued to you on the remaining balance due from your LTI's. Since it is a trust all income is reported to the beneficial ownership interests - i.e. LTI owners.
This does not mean that you actually received the cash on this interest rather the balance per LTI went up by the nominal interest rate accrued per share.
Just report the income as indicated on your K-1; it should be basic interest income reported on Schedule B or line 8.
This post is my own opinion, and should not be relied on for your investment decisions.
