Investors & landlords

It's not just a 1099-DIV, but also a 1099-INT and a1099-B. 

In  the 1099-B section, Turbo Tax asks me what type of investment it is and forces me to choose from a drop down menu one of the following:

stock

mutual fund, index fund, ETF

bond

options

 

If there is  not a requirement to enter this on the tax return, then why does TurboTax ask me?
