Hello there, @Anonymous.

Thanks for joining us here in the Community. I can help you delete a journal entry in QuickBooks.

The steps to do this will differ depending on which QuickBooks version you're currently using.

For QuickBooks Desktop (QBDT), here's how:

1. Go to Company or Accountant menu at the top, then pick Make General Journal Entries on the drop-down.
2. Click the Previous arrow to open the previous journal entry.
3. Press Ctrl + letter D on your keyboard, then choose OK to delete.

For QuickBooks Online (QBO), here's how:

1. Go to the Gear icon at the upper right, then pick Chart of Accounts under Your Company column.
2. Locate the appropriate account for the transaction, then choose View Register (or Account History) from the Action column.
3. Click the journal entry, then pick Delete.
4. Select Yes to confirm that you want to delete the transaction.

For more information, you may check out this article that tackles reversing or deleting a journal entry in QBO.

That's it! Please let me know how it goes or if I can be of additional assistance by leaving a comment below. I'm only a post away if should you have any follow-up concerns. Take care and have a good one.
