Hey there, @unicornskies
Bo here from Shopify Support!
That is a really great question. As the wrong PayPal is associated with the account I would recommend connecting the correct one immediately if you have not already:
As you already have had a payment go through you will need to contact PayPal to get it routed to the correct account. When this happens PayPal holds the funds until the email address the funds were sent to sets up an account or the merchant (you) contact them to get it routed back to the correct account. They will hold these funds for 30 days before sending them back to the customer if you do not get in touch. You can contact PayPal here. You may also need to give them some information. You can find this by going to Orders and then selecting the order in question. Scroll down to the timeline and select "information from the gateway". Here you will find any additional information their customer service may need to track down your funds for you.
Let me know how this goes and if there is anything else I can assist you with, I'm happy to help!
All the Best,
