Get your taxes done using TurboTax

This series of questions on extensions does not make any sense.  I paid my taxes. I filed an extension and overpaid at that time. When I completed my filing I got a refund. Why would TurboTax be asking these questions.  Their existence is causing me a great deal of time that I think is being wasted. I put in the amount I paid with the extension. No where does it ask what my final tax bill was, whether I got a refund or any other information that would give some sort of sense to these questions. Am I wasting my time? Should I ignore these questions? If I am not wasting my time where do I find documentation on how to treat these questions (which are not self explanatory).
