W-2 wages off by one paycheck, but all paychecks are correctly in books. How to find this paycheck that is not reflecting on W-2?

I can see the urgency of this matter, and I want to ensure this gets sorted out as soon as possible, @TOH16. Allow me to share some information about this matter. 

In some cases, you may see boxes have different amounts in each, or different compared to your employee's paychecks. These differences are sometimes correct as it may be due to the following reasons:

• Employees have a pre-tax deduction, fringe benefit, or company contribution.
• Employees earn tips.
• The employee is exempt from one or more federal taxes. 

Deductions such as retirements and pre-tax insurance plans can affect the amount in one or more boxes in the form. These deductions may be subjected to Federal Withholding, Social Security, or Medicare, which can decrease their total amount. Meanwhile, fringe benefits and company contributions are subjected to more Federal taxes, so their total amount may increase. Additionally, employees who earn tips may have different amounts as they are included in other boxes. See this article for more information: Understand why W-2 box amounts are different.

Moreover, I'd recommend contacting our Customer Live Support again to help you further with this. They have the tools to check your account securely and provide you with the necessary steps to correct your W-2 forms.

Additionally, I'm adding this resource to know more about what to do if you or your employee finds a mistake on their W-2 or your W-3: Fix an incorrect W-2 and W-3.

You can also print the W-2 forms and send a paper copy to your employees.
