If you had no tax withheld, there could be various reasons for that. But you file with what you have, and if you owe because of no withholding, then you owe.
If you had tax withheld according to your paychecks but it is not listed on your W-2, then you need to get a corrected W-2 from your employer. Don't file your tax return until you get a corrected W-2, but you should file a request for an automatic extension.
