Hello,  I have a client who does all of their day to day data input & payroll in quickbooks and they had been making double deduction of super.  The super guarantee was deducted automatically but then his wife started doing payroll and manually added in the super deduction.  How am I able to decrease the superannuation amount back to only the super guarantee amount?  I tried in the Payrun doing a negative "Adjust Super" entry but it will not accept the minus symbol.  

Thank you for any help, Fiona
