There is no “easy” way to do it. I would start by going to the routing menu while in schematic view and select all traces and then press delete. That should remove any currently routed ratsnests in schematic. Now you would place all the components where you feel like they would best sit (often in the same places as in breadboard view) Then you drag each ratsnests around and when you let go they become wires/traces. You then add bends and route everything in a clear way that is easy to follow. The entire point of the schematic is to allow you to view the circuit and it’s connections to make sure you have everything connected correctly so having it clear is really important.
Be sure to back up your current file before going any further as Fritzing has some bugs that could cause a loss of data.
Also it is not entirely necessary to make the schematic view. If you are 100% confident that the connections are correct in breadboard you can move straight to PCB view. You should always make sure the pins are labelled correctly in PCB view to match your real world parts pin order.
