I sent a previous reply but didn't see it posted. I believe TurboTax has a review, you can request one of their pros to review it for you. H&R Block also has a free second look and can review it if you take it to them.
As a tax preparer I have seen that most people are coming out the same as last year or a little better. However, if you claimed too many withholdings on you W4 then you will owe. I would suggest changing that to married 0 or single 0 and maybe have them withhold an extra $100 per paycheck.
