Hi erikhogenson-gma,

In QuickBooks, we're unable to permanently remove an account. However, we can deactivate it. With this, the account will not show on the register but, will reflect on a report. QuickBooks includes them to keep everything accurate. 

Here's how to deactivate an account:

1. From the Accounting tab, select Chart of accounts.
2. Locate the duplicated account.
3. Under ACTION, click the View register drop-down.
4. Select Make inactive.
5. Click Yes.

If you want to customize some reports to hide the inactive accounts, you can check this guide: Modify reports in QuickBooks Online.

That should do it, erikhogenson-gma. Keep me posted if I can be of assistance. I'll be glad to help you out!
