Hello there, Kathy.
Printing a bank register for a specific month is easy peasy. I'd be happy to guide you through the steps.
- Sign in to your QuickBooks Online (QBO) account.
- Click the Gear icon, then select Chart of Accounts.
- Find the checking account and click View register.
- From the filter icon, customize the date. Select 08/01/2023 - 08/31/2023 from the fields.
- Click Apply.
- Select the Print icon to print.
