You owe money because the amount of tax that you had withheld from your pay during the year is less than your total tax for the year on your tax return. You have to make up the difference when you file your tax return.
On your 2022 federal tax return, the total tax that you have to pay for the year is on Form 1040 line 24. Your total withholding and other payments that you made during the year is on line 33. If line 33 is less than line 24, you owe the difference. Look for similar lines on your state tax return.
There's nothing wrong with owing a reasonable amount on your tax return. It simply means that you did not give the government an interest-free loan. But if you would rather have the government hold more of your money and send some of it back to you at the end of the year, you can ask your employer to withhold more tax from your pay.
If you did not owe tax last year, compare last year's and this year's tax returns line by line and see where the significant differences are. That will give you an indication of what changed.
