Seems like you still owe more even with the extra withholding. All the withholding both regular and extra should be in W2 box 2. After the tax is calculated on your income the withholding and any credits are subtracted giving you a refund or tax due. Compare your return with 2023 line by line and see if you missed anything. Did you make more income in 2024?
All the federal tax withheld is in box 2 of your W-2. There is no other place that it appears on your W-2. So...perhaps you need to increase the "extra" withholding for the upcoming year.
