It's good to see you here again, @bgoon. I'll show you how to change the Markup income account setup based on your COGS.

The Markup income account depends on what you set up from the Account and Settings tab.

For the QuickBooks system to follow the setup in your COGS, you'll need to change the Markup Income account. Here's how: 

1. Click the Gear icon and select Account and Settings.
2. Click the Advanced tab.
3. Scroll down and click the Chart of Accounts.
4. After that, click the dropdown icon of the Markup income account. Then, select the account that you set up in your COA COGS.
5. Once finished, click Save and Done. 

I'll also add this article to help you match your real-life bank and QuickBooks statements: Learn the reconcile workflow in QuickBooks.
