How do I How can I correct the category rent was charged to for one month only?

Hello there, @lcaiazzo8866.Let's get this done so you can start recategorizing your transactions to the correct account in QuickBooks Online (QBO). 

Before we begin, are you referring to recategorizing transactions from your bank account? If so, we can uncategorize this entry from the Transactions tab and place it in the appropriate category. Here's how:

1. Go to the Transactions menu and navigate to the Bank Transactions tab.
2. Tap the bank tile where you have categorized these entries.
3. Click the Categorized tab and select Undo under the Action column. The Categorized tab is where transactions are placed immediately after you've categorized them into a different category.

If you're referring to transactions that were manually added to your chart of accounts, we can follow these steps:

1. Go to the Gear icon and select Chart of Accounts (COA).
2. Locate the account where the rent has been added.
3. Under the Action column, click the View register dropdown.
4. Find the specific month’s rent transaction and open it.
5. Tap the transaction and change the category in the Account section.
6. Click Save.
