Client put in after tax contributions to a 401(k) of $30k.  Now trying to roll that into a ROTH IRA as a distribution from the 401k.  For a normal IRA transfer I would put in basis info and they system handles it.  Can't figure out how to reflect correctly so he gets credit for the basis in the after-tax 401(k) contribution.  Don't want to get a matching notice from the IRS if I just remove the taxable amount from the input.
