I accidentally closed my business bank account in quickbooks. All my transactions from last year are gone. Is there a way to reverse this?

Hi there, @joeygraham2.

I'd like to help and get those data back. If you're referring to closing your bank account by toggling the radio button to OFF, you can repeat the steps and select the toggle to ON. Here's how in your QuickBooks Self-Employed (QBSE) account:

1. Go to the Gear icon.
2. Select Bank Accounts.
3. Find the account you accidentally hide.
4. In the Show Account section, select the toggle to ON.

I got you this article for more details: Delete a bank account in QuickBooks Self-Employed.

However, if you're referring to deleting your bank account, you'll want to contact our support team. From there, they can check your account securely and help you recover the data.

Also, here are some great articles you can read for future reference:
