Welcome to the Community forum, Kathryn. I'd love to assist you with this issue. However, I need additional information to give you the best solution.
Could you clarify what you meant by "book your deposit"? Are you looking for instructions on recording the deposit you've received from your customers, or is there something more specific you're trying to accomplish? Knowing the exact process you're trying to do will help us pinpoint the issue and respond more effectively.
However, I can guide you through the steps if you're trying to record your bank deposits. Start by logging into your QuickBooks Online (QBO) account and then follow the steps below:
- Go to the + New tab on the left panel.
- Choose Bank Deposit under Others.

- Fill in the necessary data you need.
- Once done, click Save and close.
