Hi there, michael24012020.
As of now the auto-fill for notes is unavailable in QuickBooks Online (QBO). Although, you can set up and create a recurring transaction template for your invoice. I'll show you how to do that.
Here's how the transaction looks like.
For more information about the recurring transactions, you an check this article: How to create a recurring invoice and manage recurring transactions.
Also, in the future, you can always change the status of your transaction by going back to the Gear icon then select Recurring Transactions. After that click the drop-down icon beside the Edit tab. Here's a screenshot for your reference.
Let me know if there are some thing that you need us to help. We're always here back you up.
