You enter the 1099-R for the 401(k) distribution.    Assuming that this is a direct rollover/conversion by the 401(k) trustee, the 1099-R box 1 and 2a amounts will be the same.    There will be no tax withheld on box 4 so you do not enter the tax anywhere.   The tax paid from another source would be entered as an estimated tax in the estimated tax section and have nothing to do with the 1099-R.

(Note: if this is not a direct trustee transfer then the trustee is required by law to withhold 20% for tax.)

BTW:  If you just took a normal distribution and the $9,200 was withheld by the trustee in box 4 on the 1099-R, then the TurboTax 1099-R  interview where is asks what you did with the money and you say you converted the entire amount, TurboTax will ask if you made up the tax from other funds.   

Thanks for your quick reply. I still have a question though. I have been using TurboTax for a number of years and I've never seen any questions on estimated tax. Is this because I've always paid the tax with the 1099? How do I find the estimated tax form?

What do you need the 1040-ES form for this late in the game? Enter the 1099-R exactly as printed. If that 1099-R shows taxes withheld, you'll still indicate that you rolled the entire amount. When asked if you made up the difference for what was withheld, indicate that you did. You don't need a 1040-ES to pay *anything* if taxes were withheld on the distribution.

If taxes were not withheld, then simply go online "right now" to www.irs.gov/directpay and pay the taxes right now.

Then you're done with the rollover stuff.
