Hey there, @psimp. Thanks for sharing your concern on the QuickBooks Community page.
Since your bank records are off due to the deleted check, we can simply recreate the transaction again to correct your balance.
- Go to + New, then select Check.
- In the Payee ▼ drop-down list, choose who you want to address the check to.
- From the Bank Account ▼ drop-down menu, select the account you want the money to come from.
- Fill out the rest of the fields accordingly.
- Click Save and close.
Please note that you need to match the date of the transaction to your bank statement. This way, you won't have a problem reconciling it in QuickBooks.
If you're not sure about this process, I suggest getting in touch with your accountant. They can provide you with the right advice to ensure your books are accurate.
Moreover, you can check out this guide when reconciling your accounts to ensure they match your bank and credit card statements: Reconcile an account in QuickBooks Online.
