Why do I owe taxes if I have w-2

[DoninGA]

No one can see your tax return.

The simplest answer is that the total tax liabilities on your tax return was greater than your total tax payments (taxes withheld)

Look at your tax return, Form 1040.

Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

How much withholding did you have in Box 2?   If you did not have enough taxes withheld or did not make estimated tax payments during the year, you have to pay the difference (check line 24 on form 1040 to see your total tax) by 04/18/23.   Or you may have made a typo, so double-check all of your entries.
