FLSA worked hours for the L&I tax for Washington state calculations

Our organization is just starting to expand our workforce into other states. One of the target states is Washington. We are having troubles setting up L&I tax for Washington. We are working with ADP and they recommended to post a question to a community as well as creating a support ticked with Oracle.

The L&I tax for Washington state is calculated based on FLSA worked hours. When we calculate the check, the taxable wages are blank and we don’t know where PS records the hours to calculate the L&I. We are not quite sure how to handle Washington L&I in PS.
