Not letting me enter past payroll checks

My main goal is to ensure you can enter your past paychecks into QuickBooks Online Payroll, userskidder.

Beforehand, may I know if you encounter any error messages when adding the prior checks to the program? Adding additional details will help us determine its cause. Sharing a screenshot would be a great help, too.

Please note that entering historical payroll information is exclusive to the current calendar year, and if no paychecks have been created for the employees yet.

Here's how you can add the checks:

1. Sign in to QuickBooks Online as the primary admin. 
2. Go to Payroll and then select Overview.
3. If you haven’t already, add all your employees in the Tell us about your team task. Include all employees that no longer work for you. Make sure to set up each pay item, deduction, contribution, and tax showing on their pay stubs or reports.
4. Beside Add your payroll history, hit Start. 

Once done, follow Step 3 in this article: Add pay history to QuickBooks Online Payroll.

If you already processed payroll, I recommend contacting our Payroll Support Team. They have the necessary tools to securely access your account and make any required changes to your pay history.

Here's how:

1. Sign in to your QuickBooks Online company.
2. Go to Help (?).
3. Select Contact Us.
4. Enter your concern, then click Let's talk.
5. Choose a way to connect with us (Start a chat or Get a callback).

Additionally, I've added an article to help view employee info, wages, taxes, deductions, and many more in QuickBooks: Run payroll reports.

You're always welcome to drop by again if you have other questions about setting up pay types and managing or tracking employee info. If you need assistance with your payroll taxes, entries, and lists, please let me know, and I'll chime in to help again.
