W2 section 12 shows HSA contribution of about $1800 (600 employer contribution, rest is pre-tax payrol deduction). Turbotax added about $600 to my tax return based on this information- since all payrol deductions are pretax, and I have not contributed any post-tax money, I don't think I am eligible for tax returns based on my HSA... any idea why turbotax is adding this amount to my tax return?
