Electrical Question about: Troubleshooting

Received from Anthony a Homeowner in Massapequa, NY

Question: I guess I’ll describe what I did and then ask the question. I wired my pool pump motor. From the house I have 110/115V going into an outdoor outlet box that contains a GFI outlet. These wires went into the line terminals. I then ran from the load terminals to the outlet for the pump. The pump plugs into an L5-20 twist lock outlet. I decided to add a switch to control the L5-20 outlet to make turning the pump off easier. I connected the hot black wire to the brass screw of the L5-20, I connected the black wire from the switch to the neutral terminal of the outlet and twisted the 2 remaining white wires (one from the incoming power and one from the switch) I also connected all grounds on the way.
Here is the question….when the switch is on all is well, when I turn the switch on it trips the GFI. Did I wire it wrong?
Thanks in advance for your help.
