Applying the deposit to the recurring payments depends on how you've recorded the initial deposit and recurring payments, @Emilys3.
If you recorded the initial deposit using a credit memo and created a recurring payment using QuickBooks Payments, note that we cannot apply the credit memo to the recurring payments as they will be processed automatically.
As a workaround, consider creating an invoice for the supposed final recurring payment and apply the initial deposit recorded with the credit memo. For detailed instructions, you can check out step 3 in this article: Create and apply credit memos or delayed credits in QuickBooks Online.
Additionally, you can set up a bank rule to automatically categorize your transactions.
If you recorded the deposit and recurring payment differently, please let us know so we can assist you further.
