just goto H&R Block. Watch them prepare your taxes on their computer. They will sit right there and ask you all the questions. They just do data entry for you.

Then when they are done and tell you what your refund will be, you can act a bit unsatisfied and not pleased. Then pickup your papers go home and do it yourself. They have a satisfaction guranteed and cannot charge you a dime until you sign a bazillion papers and pay out the arse fees.

I feel no guilt of shame in doing this. H&R are crooks and charge people way too much. Jackson Hewitt does the same.

Like others said, This is simple math really. If you miss a deduction it probably won't be a major big difference maker.
