Why doesn't turbotax show the reduced amount of my closed IRA account show on Form 1099-R? Federal tax was withheld before I closed the account.

I closed out my IRA in full and had Federal Tax withheld. I placed the 1099-R form amounts turbotax but at the end turbotax shows only Box 1 info but no Box 4 info (withholding). Why? I do not want to be taxed twice on the early withdrawal on this account.
