I qualify for HSA catch up contribution - max $4,450 for 2018. Turbo Tax is calculating a 6% tax due of $267 for over-contributing. This is wrong, I am over 55.

Did you enter an amount in the personal contribution section that was already covered by a payroll deduction?  Your payroll deductions (plus any free money from the employer) are listed on your W-2 and captured automatically.  Later in the program when you are asked about your own contributions, you should only list contributions you made directly to the HSA bank with after-tax, out of pocket dollars.

Otherwise, the amount of $267 doesn't correspond to anything I can identify (for example, if the program thinks you only qualified for 11 months, the amount would be $287.50 if you were under 55 or $270.83 if you were 55 or older).

A penalty of $267 implies that $4,450 is being treated as an excess contribution.  Examine Form 8889 to see the reason.

Did you answer the questions about qualifying insurance?  You have to run the entire interview without skipping around.

Thank you.  I reviewed again and found that I had entered the amount from my W-2 and then entered it again when I was answering questions about my HSA.  I appreciate your responses.
