Will I need to include bonus amounts if I already paid taxes on them when I received them?

You must include all of the income you received in 2021.   Your tax liability is based on the total amount of income you received during the tax year.   Your refund is the difference between the amount of tax withheld and the amount of your liability.   If the bonus is reported on some other document you must enter that document.   Or more likely it is already included on your W-2.  Ask your employer.

@xmasbaby0 is correct.

You'll get credit on your tax return for the income taxes you paid from your bonus, when you file your income tax return. Your income tax paid versus your income tax that you should have paid gets reconciled when you file.
