Retirement tax questions

I have spent days trying to educate myself enough to answer this question. It was after entering a 1099-R in which I moved money from an IRA into a Roth IRA. The question asking if I had any already taxed money in my IRA is a very confusing question as I didn’t even know that was possible. The question is worded in a very unlike TurboTax simple everyday language and more like professional tax preparer language. And my next complaint is that even when you say no to this question, you cannot bypass the next question wanting your IRA balance. It’s none of turbo tax’s business! I’m not RMD age and had dig through on-line statements for this value, as I didn’t think it was needed for my tax filing.
