Hello rafelina,
Nice to have you back in the QuickBooks Community! It's awesome that you're running payroll in QuickBooks Online and that you're using the Paper Cheques option to get your employees paid. I'd be happy to explain what to do if you've issued a cheque from the wrong account by mistake.
The first step will be to delete the incorrect pay cheques. To do that, click the Payroll tab on the left navigation menu, then select Pay Cheque List. Check off the ones to delete, then select Delete.
Now that you've deleted the incorrect cheques, you'll have to adjust your payroll account mapping. To do that, follow these steps:
1. Click the Gear icon.
2. Select Payroll Settings.
3. Click Accounting.
4. Make the necessary adjustments.
Once you've selected the proper bank account, you can re-run payroll with the corrections.
I hope this helps. If you have any other questions or need assistance with any of these steps, please don't hesitate to reach out to our tech support team.
Cheers.
