Hello, are these the same steps to use for QuickBooks Desktop? 

I had a customer make 2 partial payments on a rather large balance. When I sent him an email stating the remaining balance he gets a screen stating is invoice is $0.00 and Paid. 

Where in QuickBooks Desktop 2022 d I find "Add online payment" to create a new invoice for the remaining balance? 

Also when I create a "Need Invoice" will that generate a new invoice with the remaining balance? Will that throw off my balance?
