There are payroll items for the company paid Medicare and Social Security. The amounts for these two items are booked to account 5505 FICA expense. I am trying to determine what tells Quickbooks to put these amounts in account 5505.
GO to Employees > Manage Payroll Items > Select View/Edit Payroll Item List
You will see Payroll Item List for payroll entries.
Locate and double click > Social Security Company > click Next > You will liability accounts set-up > click next > this is where expense account is setup for FICA expense. Make account change here.
