Get your taxes done using TurboTax

To be clear:

2019 is OK.  Placing the amount in box 14 is technically wrong but has no effect on your tax return as long as box 1 and box 12 are correct.

 

For 2018, you might need to amend if your voluntary payroll deduction HSA contributions were not included in your box 1 wages (were removed from your pay pre-tax).  If box 1 did not include those monies, then you took a double deduction (you deducted money from your income that was already not in your income) then you should amend and pay the extra tax.
