The answer is generally "you pay ADP to do that for you so you don't need it in Sage 50".  You should be able to get the same reports from ADP.

Because you imported as a general journal entry, the payroll module does not see the information (and no, I do not know of a way to import as a payroll cheque).  If you really want to duplicate what ADP is doing, you can enter them manually in the payroll module if you have a subscription to the module.

We have been using Sage for a while but only with ADP for a month.  So I just wanted Sage to reflect the same info as ADP. Maybe I'm overthinking this.
