I will add a note that if you want to pay the tax from the IRA (usually better to pay the tax from separate funds) you would enter the Federal tax you want withheld into box 4 and state tax withheld in box 15 and the state in box 12.
The withholding will be part of the taxable distribution but not the conversion so there will be less to convert, but you pay tax on the total distribution including anything withheld for tax.
