what is in Box 7?   I had a client just this year, tell me the same story, but i happened to know her NEW broker, and upon further review, she brought in a check to him.   Not saying that's the situation in your case. So I just put the taxable amount the same as the withholding amount, and then  went to the Misc Statement form and explained what transpired in reality... that the taxpayer had timely rolled over ALL the funds of the IRA except the income tax withheld.  and that is what happened, taxpayer got credit for the amount of W/H... which more than covered the income tax on that amount.
