1099-MISC for interest payments on loaned stock

I received a 1099-MISC with an amount shown in Box 3: Other Income. This 'income' was from Fidelity as they paid me interest on shares I owned and loaned to them to cover shorts made by other Fidelity customers. For whatever reason, Turbo Tax is trying to force me to include a Schedule C for business income ... but this is not business income, it is personal investment income.  How can I get Turbo Tax to treat this 1099-MISC as investment income so I'm not required to file a Schedule C? There are some boxes on Schedule C that I cannot provide an answer to because they don't exist... Like principal business code and accounting method.
