How do I delete multiple payments to an invoice at once instead of having to delete them individually?

Hello, ttriggs. 

In QBO, you’ll have to unlink invoice payments one at a time. This is to avoid the accidental removal of another transaction. 

Though, through our Feedback board, we can pass a request here about this feature. Just go to the Gear icon and choose Feedback. These requests and suggestions are forwarded to the Product Development Team. And I want to let you know that your voice matters, and each update our developer team creates are considered that it benefits our customer's business.   

You may also want to visit our QuickBooks Online Feature Requests site to track product requests submitted for the program.  

For future reference, here’s a link that outlines the complete steps on how to associate a bank deposit to an invoice. Additionally, this guide contains resources to help efficiently manage customer transactions in QBO: Sales and customers. 

Also, you can always visit our Help Articles for QuickBooks Online in case you need some tips and related articles for your future tasks. 

I appreciate your patience as we work through this. If there's anything else I can do for you, please let me know. I'll be around to help you out. Stay safe!
