Can't find/edit reoccurring invoices

I'd be glad to help you find the recurring invoices in QuickBooks Online (QBO), grif220736. 

To access recurring transactions, simply click on the Gear icon and choose Recurring Transactions from the List column. From there, you can filter by Transaction Type to Invoice and then select Edit to make changes to the due date

I've added screenshots for your reference. 

You can check this article for more information on how to Schedule recurring transactions. Schedule recurring transactions created with a template.

I will also include a helpful article that guides you in receiving and recording invoice payments: Record invoice payments.

Feel free to let me know if you have any questions about editing recurring invoices. I'm always here to assist you. Have a good one
