TurboTax is exceptionally good. Not sure why anyone would have problems with the SS deductions. I work a job where I do not have SS deducted, but I have Medicare deducted and TurboTax makes it very easy to handle. TurboTax has the advantage of flagging items that either are mistakes or seem out of whack. Not sure that irs.gov will do that part for you. I have used TurboTax for over ten years and have been exceedingly happy with the product. I can tell you also that it is the #1 program among professional tax preparers (I'm not advertising for TurboTax and have no vested interest in the product, I just work with a lot of paid preparers from multiple states).
