How can I map my chart of accounts

You will be able to map the Zenefits Payroll transactions to your accounting chart of accounts in the Settings tab of the Payroll app. If this is your first time setting up the sync, in the Organization tab from the left-hand menu, you will see the option to add accounting software by clicking on the orange Sync button.

To properly export the information, every transaction type MUST have an associated account. Even if you are not using the transaction type now, the mapping must be completed for the export to work correctly.
