Hello @thekesselcompany,

You'll have to delete each transaction manually to fix this. However, you can delete your transactions in batch. Let me walk you through how.

For invoices, here's how:

1. Go to Sales, then Invoices.
2. Check the box next to Invoice. This will mark all the boxes of all invoices.
3. Click the Batch actions drop-down, then Delete invoices.
4. Snap Delete when prompted.

For expense and other vendor transactions, you'll have to open each one of the transactions to delete it. Please see this article for details: Void or delete transactions in QuickBooks Online.

You can also check our page for additional reference of our future task: Income and expenses.

Stay in touch if you need help with anything else. I'd be sure to jump in as soon as I can. Thanks for posting and be safe.
