Good evening, @wyliehawkins99. 

Thanks for dropping by the QuickBooks Community. How are you today? I hope everything is going great. 

The only way to reconnect the invoice payments to sent invoices would be deleting and recreating the payments. I'm including some steps below to walk you through the process. 

To delete the payment: 

1. Locate the payment. 
2. Under the Action column, tap on Delete. 

To recreate the payment: 

1. Navigate to the "Transactions" section in QuickBooks Self-Employed. 
2. Click on Add Transaction.
3. Choose the transaction type. 
4. Enter the payment details. 
5. Hit Save. 

That should get you back on track. For additional information and tricks and tips when using QuickBooks Self-Employed, check out our Beginner's Guide. 

Please let me know if there is anything else I can assist you with. Have a good one!
