Thanks for sharing the feature you'd like to add in QuickBooks, KristaLan. I can see how the functionality to edit your remittance slip would be beneficial to your business.

As of now, the ability to edit your remittance slip in QuickBooks Online is unavailable. I'd recommend sending a feature request directly to our Product Development team. This helps us improve your experience and the features of the program. 

Here's how:

1. Go to the Gear menu and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.
   

You can also track feature requests through the Customer Feedback for QuickBooks Online website.

Additionally, I've included this article that'll give you a snapshot of your business. This way, you can ensure your record is accurate: Run Reports in QuickBooks Online

You can count on me if you need help in managing your reports or transactions in QuickBooks. Take care and have a good one.
