I'll walk you through the steps on how you can reprint your paychecks, amydrost. 

Let's go to list of paychecks and select the paychecks that were printed incorrectly. Here's how:

1. Go to the Workers menu and proceed to the Employees tab.
2. Click Paycheck list in the right-hand side, just below the Run Payroll button.
3. Select the correct date in the Funnel icon.
4. Check the boxes of all paychecks that you want to reprint.
5. Click Print.
