I am an accountant and need to make reversing journal entries. How do I do that?

It's good to see you here in the Community, @jolson-integrate. I can help you with how to reverse the journal entry in QuickBooks Online.

Reversing a journal entry automatically is currently unavailable in QuickBooks online. We can only reverse them manually. 

Here's how:

1. Sign in to QuickBooks Online and log into your Accountant Company.
2. On the left navigation bar, click the Accounting tab.
3. Choose Chart of Accounts and find the journal entry you created and double-click the account.

4. Click the Journal Entry option under the Transaction Type.

5. Select the Reverse option from the ribbon below.

You can also check out this link for further instructions if you are using the QBO company.

I added some help article that you can use as your future reference on journal entries:
