You say "estimated taxes" but do you really mean that you had tax withheld from your IRA distribution? Tax withheld from the distribution is not estimated tax, it's withholding, just like tax withheld from a paycheck. Estimated tax is the quarterly tax payments that some people make if they do not have any tax withheld from their income. If you make an estimated tax payment you have to send the payment to the IRS yourself. It doesn't matter where you get the money to make the estimated tax payment.
If you had federal tax withheld from your IRA distribution, the IRA custodian sends the money to the IRS. The amount will be shown in box 4 of the Form 1099-R that you get in January. All you have to do is enter it in box 4 in TurboTax when you enter your 1099-R, just as it is shown on the 1099-R form.
