how can i cancel a payroll run or edit a deduction (cancel) after the payroll run had been submitted?

You can still cancel or edit your payroll if it hasn't been submitted yet, @RMJENTERPRISE2024. But in your case, you have the option to void it or create a new one instead.
 

Here's how to void a paycheck:
 

1. Go to Employees, then to the Paycheck list section.
2. Choose the paycheck you want to void.
3. Select Void from the Make adjustment drop-down.
4. A prompt will appear. If you agree with the terms, click Void Paycheck.
   
   
   
   

Please note, your ability to edit, delete, or void a paycheck will depend on your payroll processing time. Refer to the screenshot below.

Additionally, you may find this guide useful for future reference: Create a payroll summary report. It provides a clear overview of total payroll, including employee taxes and contributions.
