Cash in lieu of stock ratio

A merger resulted in cash being added to my in-house account at TD Ameritrade. The statement for that period does not show that I got any stock in the merger; it says PURCHASE FDIC INSURED DEPOSIT ACCOUNT. In TurboTax, select "I received cash in lieu of fractional shares as part of a merger....". Now I'm confused when I'm asked "Ratio of new shares to original shares". What do I put there since I received no shares?
