Welcome to the Community, George.
QuickBooks Online (QBO) doesn't have the spelling checker feature. However, we can turn this feature on in the browser settings.
Here's how:
- Click the ellipsis ⋮ icon in the upper-right corner of your browser. (Google Chrome or Microsoft Edge)
- Select Settings.
- Under the Languages section, turn on the Spell Check option.
I've added the screenshot for your visual reference in both Google Chrome and Microsoft Edge.
Enabling this feature will prompt the browser to automatically check for spelling errors.
Additionally, I've added this article to help you learn more about how you can manage your account in QuickBooks: Help Articles.
