I processed payroll twice for an employee....how do i fix it?

I can help you void this direct deposit, @pc4square. 

QuickBooks Desktop Payroll has a 2-day lead time. This implies you must submit payroll two business days prior to payday by 5:00 PM (PST). After you’ve submitted payroll, you can still void it up to 4:59 PM PST that day. After 5:00 PM, payroll begins processing and can no longer be voided. 

To void the direct deposit check:

1. Go to the Employees menu and select Edit/Void Paychecks.
2. Change the Show paychecks through/from dates to the date of the paychecks you need to void, then press Tab on your keyboard.
3. Click the check-in question and select Void.
4. In the pop-up box, enter YES and select Void.
5. Click the checkbox to agree to the terms and conditions of voiding the paycheck.

Once done, send the voided paycheck to let our system know to cancel the paychecks. Here's how:

1. Go to the Employees menu and choose to Send Payroll Data.
2. Click on Send. 
3. Provide your payroll PIN and click on OK.

Check out this article on how to cancel, delete or void payroll paycheck or direct deposit payments after they're submitted: Delete or void employee paychecks. 

If you can no longer cancel the direct deposit, your employee will receive the money in their bank accounts on the pay date. You can set this as an advance payment or consider requesting a direct deposit reversal: Reverse a direct deposit. 

Let me know if you have follow-up questions about voiding this direct deposit check. I'll be here and ready to help anytime. Have a good one!
