Hi there, @af123.

You'll have to go to your banking page if you've connected your bank account to your QuickBooks Online (QBO). From there, you have the option to exclude duplicate transactions. Let me guide you how.

In your QBO account:

1. Go to the Banking menu and select the Banking tab.
2. Select your Home Depot account.
3. Put a checkmark beside the Date column in the For Review tab to select all transactions.
4. Click the Batch actions drop-down menu and select Excluded Selected. 

I got you this article that you can read for more details about excluding transactions: Exclude expenses from downloaded bank transactions. This will guide you detailed information in excluding downloaded transactions.

Otherwise, if the transactions are already in your Chart of Accounts (COA). You'll have to click on the View register link to delete each duplicate transactions. 

Here's how:

1. Go to the Accounting menu and select Chart of Accounts.
2. Locate your Home Depot account and click View register.
3. Click on each duplicated transactions and select Delete. 

Also, I recommend getting in touch with your accountant for guidance in deleting these transactions. This way, we can ensure the accuracy of your accounts after making these changes.

I'm also adding this great article that can guide you in reconciling your accounts in QBO: Reconcile an account in QuickBooks Online. This link provides detailed information on how to make your books accurate when reconciling.
