After you file

That doesn't make sense. I have filed my last 5 returns with TurboTax.  If they can tell me how much I owe every year then why wouldn't it show how much I owe this year. Also if they can tell me how much I will receive from federal/state why would it not be able to tell me how much federal or state wants from me to pay back? I found a similar question below on TurboTax and they said if you owe back taxes it will withhold it from how much they are going to give you.
