Where do I enter Federal Taxes already paid on IRA Distributions? My 1099-R shows taxes prepaid however TurboTax does not take this into account.

The federal taxes withheld in box 4 of the Form 1099-R are entered on your Form 1040 on Line 25b.

Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

Did you enter it from box 4 when you entered the 1099R?

You didn’t actually pay the tax or the 10% penalty (you pay a 10% early withdrawal penalty if you are under 59 ½). You had taxes withheld like from your paycheck. You still have to enter the whole gross amount (before taxes were withheld) with your other income to figure out the total tax (and it may put you into a higher tax bracket) and then the withholding is subtracted from the total tax to figure your refund or tax due. The Gross amount shows up on 1040 line 4a or 5a and the taxable amount on 4b/5b.  You will get credit for the withholding on 1040 line 25b.
