Yes, you have to enter the Form 1099-R that you received on your tax return. The taxable amount of the distribution in box 2a is added to your tax return as ordinary income and taxed at your current tax rate. The federal taxes withheld are entered on your tax return as a tax payment.
This is no different then entering a W-2 on your return for the gross amount of income and the federal taxes withheld.
