Hello there, bcwtup,
Changing an expense transaction to deposit is unavailable. You'll want to exclude this transaction instead. Then, record a bank deposit.
- Click Banking on the left pane.
- Select the Banking tab.
- Choose an account.
- Go to the For Review tab.
- Put a check mark beside the transactions.
- Click the drop-down arrow from the Batch actions.
- Select Exclude Selected.
Once done, manually add them in your bank register.
Here's an article for future reference: Reconcile an account in QuickBooks Online.
