After e-filing, I noticed TurboTax provided a different amount on Form 1040 Line 2 ("Health savings account deduction") and Form 8889 Line 9 ("Total contribution made in 2018"). This deduction/contribution is a number that I didn't enter into TurboTax.
Per the IRS, Form W-2 Box 12 Code W reports employer contributions to an employee's HSA. However, my employer included both the employer and employee contributions in 2018. Is this correct? I didn't make an contributions using a "cafeteria plan".
Regardless, when completing my tax return online, TurboTax asks for the amount in Box 12 Code W. It then asks for the employee contribution amount that makes up the total contribution amount. Is the difference what should appear on Form 1040 Line 25 and Form 8889 Line 2 since Form 8889 Line 9 asks for the employer contribution separately? Despite the error, the end result is the same (no additional tax).
