A rollover/conversion of after-tax 401(k) money to a Roth IRA is tax free. Have the 401(k) trustee do a direct rollover to the Roth IRA which should be reported to you with a 1099-R with a code G [typo corrected] in box 7 and the taxable amount in box 2a. The after-tax contributions should be shown in box 5 and if that is the same amount as the total rollover shown in box 1 then box 2a should be zero.
