Hello there, @accounting-JE. I appreciate you bringing this to our attention. 

The steps provided by my colleagues above regarding the Customize button and Import Style feature is for QuickBooks Online (QBO). 

If you're using QBO, then you should have those options. To isolate the issue about the missing buttons, let's use a private browser. Since there are instances that the stored cache cause issues if it gets full of outdated files.

Here's how to open it:

• Chrome: Ctrl+Shift+N
• Firefox: Ctrl+Shift+
• Safari: Command+Shift+N

Once done, try to follow the steps provided above. If it works, then your main browser causes this kind of issue. To ensure this doesn't happen again, it's a good idea to clear the cache of the browser you're using.

However, if those are still missing, I'd like to ask what version of QuickBooks were you using? I want to ensure I'd be able to provide the right fix for this problem. 

Please keep me posted how things go on your end. I want to ensure this gets resolve for you. I'm always here to help. Take care.
