Get your taxes done using TurboTax

I appreciate your feedback. I am trying to determine on my W-2 if an HSA deduction was made. I currently already have a corrected W-2 that reflects an approximately $50 decrease in boxes 1,3,and 5 due to a payroll error. I see a figure in box 12c (W) on the original W-2 that represents the original maximum HSA contribution that I made. How do I tell if a deduction has been made and to what figures do I apply a manual correction? Thanks.
