Why does Turbo Tax list my non-taxable Roth IRA distribution as income in the income categories without telling me that it is not taxable?

I KNOW my Roth distribution is non-taxable because I meet all the requirements -- more than 5 years, over 59 1/2, etc. But I still don't know if I should have entered it in Turbo Tax because it is showing up as income in the income section. It would be helpful if Turbo Tax would provide more guidance in this case, such as: "Only enter a Roth distribution if it is taxable..." or "Enter any Roth distribution and we will tell you if it is taxable or not..." So I'm hesitant to continue with the return until I know if I've entered this Roth IRA distribution properly.
