Get your taxes done using TurboTax

I'm not looking for a safe bet.  I want to know what my taxes will be and how to adjust my withholding so I get the level of refund that I prefer.  I'm in a high tax state where property tax alone breaks the $10k ceiling.  Then there's state income tax.  Supposedly TT P has the ability to tell me this.  It does have the W4 calculator but that doesn't tell  you whether it is meant to just break even or what the result would be.
