Thanks for posting this concern in the QuickBooks Community, @chyrchel74,

Allow me to join the thread and share some steps to help you further with the Undeposited Funds (U/F) corrections. Yes, when you deposit the correction to the operating account, it will increase the register's balance.

To avoid affecting your account balances, you can use a clearing account to transfer the amounts. Here's how to add a dummy account:

1. Select the Gear icon, then select Chart of Accounts.
2. Press New.
3. Under Account Type column, select Bank. Under Detail Type column, select Cash on hand.
4. Add a name called Dummy Bank.
5. Once done, save the information.

When you're ready to make an account inactive:

1. Go to Settings ⚙ and select Chart of accounts.
2. Find the account you want to delete.
3. Select the Action ▼ dropdown and select Make inactive.

If you have further questions or concerns about this Undeposited Funds topic, please let me know in the comment below. I'll be right here to guide you further with the corrections. All the best!
