Good day @Br1z1

 

After finding the correct, three computers and battling Courtney, you need to make your way back to Wattson at New Mauville. Once you get there, speak with him to complete the quest. 

 

For a guide, here is an updated Hoenn Transport Quest guide that you can reference as well.

 

I hope this information helps and look forward to hearing of your success.
