How to find check book register with on line version for making entries like the desktop version has.

Welcome to the QuickBooks Community, Bob_. 

I'll ensure you can quickly find the checkbook register in QuickBooks Online.

I recommend going to the Chart of Accounts, where you can search for and find the Checking register.

Here's how:

1. Click the Gear icon at the top.
2. Choose Chart of accounts.
3. You can use the search bar to find the Checking account.

Once completed, you may click the View register link to open the Bank Register page. You'll then be able to easily create several entries within the section. I included screenshots below for visual reference.

In case you need guidelines on how you can review your transactions and make quick edits so the details are up to date, you can read this article: Find, review, and edit transactions in account registers in QuickBooks Online.

Please let me know if you need clarification about this, or if there's anything else I can do for you about managing bank accounts in QBO. I'll be standing by for your response, Bob_. Have a great day and be safe!
