Hello, @ValkyrieAnne.

I appreciate the idea you've shared about tracking payroll items in QuickBooks Online (QBO).

I'd suggest sending our Product Developer a feedback through your QBO company. Your valuable feedback goes to our Product Development team to help improve your experience in QBO. 

Here's how to send feedback:

1. Log in to your QBO company and select the Gear icon.
2. Click Feedback.
3. Enter your suggestion such as "It would be great to add Payroll Item tracking on the Reports (explain why)."
4. Select Next. This is how it looks like;

The more request it has, the more likely it'll be added on the next update. 

I'll be around the Community page if you have other questions. Feel free to tag my name in the comment section. Take care!
