Hello Monika1983,

Welcome to the Community. Allow me to help figure out the transaction journal result of the purchase invoice in QuickBooks Online.

Can you share with me which specific report shows the COGS amount and includes the purchases? Any additional information you can add will ensure a timely solution.

Your bills will reflect on your COGS account once you add it as a category on a transaction. Since the item setting is correct, I suggest you go to your Chart of Accounts and review the purchase invoices showing on the report.

Here's how:

1. Click the Gear icon in the upper-right corner.
2. Below Your Company, select Chart of Accounts.
3. Search for the Cost of Goods Sold account.
4. Below the Action column, click the Run report option.
5. Click to open the bill.
6. Review the details.

Please check out the sample screenshots below:

If you want to know more about the source and targets for running reports, check out the article I found helpful on this:

Targets vs. Sources overview.

Please don't hesitate to add more information or screenshots if you need further help with the reports. I'm always up to lend a hand.
