Is there a way to process payroll checks that were missed in 2021?

Yes, there's a way how to process payroll checks that were missed in 2021, @Shatiowens.

We can process a late payroll, otherwise known as backdating paychecks. Simply run an unscheduled payroll using the actual pay date. 

Here's how:

1. Select the  Payroll menu, then choose Employees.
2. Click Run payroll.
3. Find the employee you want to pay, and then select Create another check.
4. Enter employee compensation, including any salary adjustments, vacation or sick hours, and other pay types.
5. Confirm the pay period and check date.
6. Choose Preview Payroll, and then click Submit payroll.
7. If creating a paper check, handwrite or print the check and give it to the employee by the check date.
8. Select Finish payroll.

For more insights, please see this article: Process a late payroll (backdate paychecks). 

If the system would not allow you to process missed payroll, I suggest contacting our support team directly. They have the tools to review your account in a secure environment and help you with processing the paychecks. For detailed steps, please open this link: Contact payroll support.

I'm also adding this resource to see the complete list of available payroll reports in QBO: Run payroll reports. It includes details about customizing, printing, and marking your payroll reports as your favorites.
