Can i change a journal entry to an expense after inputting it from account register?

Welcome to your first post, kmannning3! The best way to fix this is by first deleting the Journal Entry, then recreating it as either an Expense or a Check. I'll provide you with a detailed guide through each step of this process.
 

In QuickBooks Online (QBO), you can't directly change a Journal Entry to an Expense. You will need to first delete the journal entry and then create a new transaction as an Expense or a Check, using the exact same details. Before deleting the Journal Entry, please make sure to note all the relevant information so that you can accurately recreate it. This will help ensure that your financial records remain consistent and accurate.

Here's how:

1. Navigate to the Gear icon, then Chart of accounts.

2. Find the account you created the journal entry for and then View register.

3. Locate the journal entry in the account register.

4. Open the journal entry to expand the view.

5. Select Delete.
6. Hit Yes to confirm.
