Under what summary? On Turbo Tax or on a broker summary statement? Why are you looking at a 1099Div for it? You might have a consolidated 1099 statement. That will have sections for 1099-Int and 1099-Div and 1099B. You need to enter each section in the right place. So read it carefully and look for headings.... 1099-INT for interest or 1099-DIV for Dividends or 1099B for sales. If you are using a statement wait for the actual 1099 tax form to come in late January or February.
