I'm here to give you some insights about removing an account, @ta43.
In QuickBooks, you won't be able to remove an account but we can make it inactive. If an inactive account has transactions for the reporting period, it will always show in reports. However, if the inactive account has a zero balance, some reports will allow you to exclude zero balance accounts.
Go to Reports.
Enter the name of the report in the Find report by name field.
Click on the Customize button.
Select a reporting period.
In the Show non-zero or active only drop-down button, select the Non-zero option.
Click Run Report.
The screenshots below show you the last four steps.
