Welcome and thanks for asking us here in the Community, @sopphirebobby. Your expense categories will appear as "-Split-" if your transactions (Purchase Order) have multiple line items.
You can pull up a certain report and view the details of the line items and the accounts connected to it by selecting the transaction. Then, you'll be routed to the transaction window where you can review its information.
Moreover, you can also run the Transaction List with Splits. Here's how:
- Go to the Reports menu, then search for Transaction List with Splits.
- Select the Customize button, then set the date range in the Report period section.
- Change the columns by selecting the Rows/Columns drop-down arrow.
- Select the specific information you want in the Filter drop-down.
- Click Run report.
Once done, you can memorize the Transaction List with Splits report to save its current customization settings.
For the detailed steps, kindly refer to this article: Memorize reports in QuickBooks Online. It also contains information on how to set a schedule and email the memorized report.
Feel free to post any concerns here in the Community by leaving a comment below.
