Thank you for getting back to us, mamnazeer.

Let's make sure you can use the import style option for QuickBooks Online.

Make sure you're also logged in as admin in the QuickBooks Online. Some of the standard user role may have limited access to different parts and features in QuickBooks. Here's an article for more information: User roles and access rights in QuickBooks Online.

If you're already logged in as admin but you still cant see the option to import style option, we can perform some of the troubleshooting steps to make sure there are no browser related issues. Let's start by accessing QuickBooks Online in a private/incognito window. Use the keyboard shortcuts below to open one:

• For Mozilla Firefox: press Ctrl + Shift + P.
• For Google Chrome and Microsoft Edge: press Ctrl + Shift + N.
• For Safari: Command + Shift + N.

If you can see the option to import styles while using a private window, then that's good. We can go back to your regular browsing window and clear it's cache. This will remove outdated and corrupted internet files that's causing some unusual behavior.

Alternatively, you can check out and use other supported browsers that works perfectly with QuickBooks Online.

I'll be around if you still need assistance or if you still have other questions about importing styles. Have a great day!
