Termination wages

Am having to do a termination pay (never done one before) which includes about 5 weeks holiday.  My accountant said to do the weeks' pay as normal then enter holidays as unused leave.  My question:

I calculate the last pay week which would then add in auto the hourly calculated leave due for that week. So,

when I enter the pay I select the check box terminate pay? Then I process another pay for the leave which should have an item unused pay?  This will then have the total calculated leave due including the last week.  But I was told not to calculate super on unused pay.  HOW DO I CHANGE selections to prevent that happening before I do the unused pay.  Also how do I ensure the auto calculated leave is cleared in at balance (in case of rounding etc.)

Lastly sick leave is not transferred if not used.  How do I zero this with the last pay?

Thanks in advance
