W2 State wages and GTL

For 2018, the GTL benefit calculation was changed to be calculated in-house and attached to employee pay instructions via the Benefit Administration Module.  For the 1st quarter, the GTL was provided as a flat dollar amount from the benefit admin 3rd party vendor in a file that was processed before every payroll so the PDBA was setup without the GTL button checked in the US/Leg Reg setup application.  However, when the new GTL PDBAs were configured to calculate in-house, it was setup according to Doc ID 655951.1, setting up a Basic LIfe PDBA to capture the first 50K, then the GTL for the excess Imputed income, with GTL button checked and Track DBA by Tax Area also checked.  This created the GTL records in the F06148 that is later used for W2 purposes, to Special Handle the GTL back to the state wages (adjusted taxable wages) where it is exempt as per Vertex.  In other words, throughout the year, during payroll, the GTL Imputed Income appears on the employee's paychecks, however, excluded from taxable gross, not taxed in Federal A wages or State F wages, and
