Hi there, @assistant1.
I can share with you some information about uncashed checks in QuickBooks Online.
The uncashed check in QuickBooks Online is not yet cleared in your bank. We can create Bank Deposits and deposit it using the same expense account as the check. Then clear them both when you reconcile it.
Here's how to manually clear these transactions in your bank register:
- Go to the Gear icon, then choose Chart of Accounts.
- Locate the account of the transaction.
- Select View Register from the Action column.
- Identify the transaction to clear.
- Under the reconcile status column, select C for Cleared.
- Click Save.


For other reconciliation resources you can check these guidelines:
Should you have any additional questions or concerns, the Community and I will have you covered. Thanks for reaching out. Have a great day!
