Ran payroll checks twice for each employee. so it shows they got paid twice in a week. Also i paid double on payroll taxes. how do i resolve this issue

Let me help you resolve the duplicate payroll transaction, tchplbg2.

We can void or delete the duplicate paychecks you created for your employees. This way, the double payroll taxes, and employee's payments will be removed in QuickBooks Online (QBO).

Here's how:

1. Go to Reports. on the left side menu.
2. Enter the Paycheck List in the search report field.
3. Under Paychecks and Pay stubs, choose the date range.
4. Select the paychecks you want to delete or void.
5. Tick the Void or Delete. down below
6. Tap Ok.

For more details about this one, check out this article: Delete or void paychecks.

If the duplicate payroll taxes go through, it will result in a tax overpayment. Just follow the steps and details in this article to troubleshoot the issue: Resolving a tax overpayment.

If you can't void or delete the duplicate transaction, I'd suggest contacting our Payroll Support Team. They'll pull up your account in a secure environment and help you with this one. You can request a callback from our support agent so you won't have to wait on the line.

Here's how:

1. Click the Help icon on the top right. 
2. Tap the Contact Us button at the bottom. 
3. Enter a short description of your concern. 
4. Tick Continue. 
5. Choose Get a callback to connect with our support.
