You can request to have any amount of the distribution to be withheld to pay the tax, but that will also be part of the taxable distribution and it is less money to put in the Roth. It is best to convert all the money and keep it growing in an IRA if possible, if you have other funds to pay the tax with. You can pay it as estimated tax using other funds.
