Get your taxes done using TurboTax

Is there a difference in deduction if I file married filing jointly or married filing separately? I thought that since I got married and my wife is financially dependent on me that I would receive a larger tax break but my deduction is lower than what it was last year when I filed as single. Since I used turbotax delux and filled out the forms as married filing separately, it wouldn't allow me to input my student loan interest either. Will I see a larger reduction / larger tax return if I go through all the steps you outlined for filing jointly?
