Royalty Income from Equities

I own some shares of BP Prudhoe Bay Royalty Trust and have a 1099-MISC from my brokerage firm reporting royalty income.  When I enter the 1099-MISC info into TurboTax, TT attempts to force me to associate that income with either (1) a property I own, or (2) royalty income from my business.  This royalty income is from NEITHER of those choices and is causing TurboTax to hiccup and not allowing me to continue progressing my return.
