Season Sales - Reporting on Ticket Layers

So I am very very very new with analytics and just trying to learn by watching past videos but I don't see anything on how to pull out information by ticket layer.  All of our tickets include a $3 historic preservation fee layer but we need our reports to be based only on the ticket layer GLs only.  Can you please point me in the direction of a video or help file that would help me learn how to build Dashboards/Widgets that would provide just this information?  Thank you!
