please see the below it might help you/others as well to give you the solution,
1. execute wagetype reporter for the EE 17000104
2. look for the amount - 26600
3. check which wage type is associated with 26600
4. if you find any wage type with the amt 26600
5. goto table V_512W_D find out the wagetype posting related config
5. then goto table V_T52EL to find out the symbolic account
6. then goto tcode OBYE & OBYG to find out the G/L account
in each step check if you are missing anything
remember if you change any setting then only if you rerun the payroll again then it will work correctly --- do not rerun the payroll if you are in production environment
