So the only way to delete a payroll paper check is to call into IT?

You can delete a paper check in QuickBooks Online, sherry_pottorf.

There's a delete option when you want to remove a paycheck. You can follow these steps to remove the paycheck:

Here's how: 

1. Go to the Workers menu, then Employees. 
2. Click the Paycheck list link. 
3. Check the box of the employee's name, then click Void or Delete.
4. Follow the on-screen instruction on deleting the check, and hit Continue. 
5. Mark check the box and press Void paycheck.

The system automatically recalculates your tax liabilities after a check is deleted or voided. If you've already made a tax payment, you may end up with an overpayment. 

We'll automatically apply any overpayments toward future liability within the current quarter. Check out this link for additional information: Resolve a tax overpayment.

If this function isn't showing up on your account, you need to contact our QuickBooks Live Support Team. They can delete the paycheck so you can create a new one when needed.

Let me know how the contact goes by commenting below. Or post again if you need anything else concerning payroll.
