Hi @karen-j-c3-llc-n,
I'll take care of your query on how you can enter the changes by your accountant.
Since QuickBooks Online (QBO) is a web-based application, any changes made by its user are saved in real-time. With that said, you have the option to invite your accountant. This way, they can log in to your company and make changes as necessary. You won't need to manually enter the changes at this point.
Should you proceed with this, you can share this article with your accountant: About QuickBooks Online Accountant features. It's a list of features available for QuickBooks Online Accountant so they can become familiar with it.
Direct other questions you have in the comments below. I'll be sure to get back to you.
