When the A/C is turned on, I can feel and hear air coming from where the smaller line enters. I found my leak, but I don't know how to fix it. I have attached a picture of where I believe the leak to be.

It sounds like you have a seal that has failed between the HVAC box and the firewall. This means the entire box will need to be removed or you can try to push a small amount of silicone rubber into the hole and allow it to dry before checking it to see if that will stop the HVAC air from leaking outward. Let us know what happens and please upload pictures or videos of the problem.
