Generally, difficulties with HSAs in TurboTax have been rooted in the opaque and arcane IRS rules, and the tremendous amount of disinformation on the Internet about HSAs. This means that the TurboTax HSA doesn't work the way you think it does.
How many years are we talking about? What kind of what HDHP coverage per year? What were the contributions each year? Where they through the employer (code W in box 12 in the W-2) or made directly to the HSA custodian? Were excess amounts caried over? Any Medicare? Spouse? How many HSAs?
I can fix most HSA returns, but I'll need a lot of details from you.
