Welcome to the Community. I'd be happy to help share some information about deleting an entry in a deleted account.
If you're trying to delete the transactions from a deleted account in Chart of Accounts, you need to reactivate it first to do that. You can only edit or make changes on the active accounts.
To start, let me walk you through on how to make the account active:
On the left pane, select Accounting.
At the top, click the Chart of Accounts tab.
From the Chart of Accounts page, click the Gear icon above the ACTION column.
Put a check on the Include inactive box.
Select the account you want to reactivate, then click the Make active link.
After that, please follow the steps below to delete the transactions:
From the Chart of Accounts page, select the account.
Click the View register link.
Select the transaction, then click Delete.
Click Yes on the pop-up message.
Once done, you can make the account inactive again. However, if you're referring to the transactions from a deleted account on a report, they are still part of your company data, and you can find them in the reports.
To stop these transactions from showing on the reports, I recommend following the steps provided on this article based on how you want to remove them: Remove deleted accounts from reports.
