Retirement tax questions

I see.  My plan allows withdrawals and I also checked and I can do a roll over to a Roth IRA.  When doing the withdrawal it shows me that taxes will be withheld (20% fee and 3% state) but when doing the rollover to Roth IRA it doesn’t show any tax liability.  If I do the Roth IRA Rollover there will definitely be a tax liability right?
