It's nice to have you here in the QuickBooks Community, @Boetheo.

I can share some insights with the new chart of accounts set up in QuickBooks Online.

When you create an expense account, you will need to pick a category in the Create category under options. This doesn't mean that you are creating a sub-account. That selector allows you to choose an account type to set up.

After selecting the account type called Expenses, you will need to choose the detail type that's closer to how that account is to be used for. If you're unsure, you can choose General business expenses. Please note that detail types does not affect the posting of your account. QuickBooks will use the main account type or category for your financial reports.
