I receive a handwritten checkbook ledger after the end of the month from my client. Trying to post payroll for December 2021 in January 2022, not allowed and now payroll forms are off.

Hello, DLW5. I've got you the steps on how to enter previous payroll.

If there are no paychecks created yet, here's how to edit prior payrolls: 

1. Go back to Payroll and select Finish adding your team.
2. Select the employee.
3. Scroll down and select Enter [current year] prior pay details.

You can also refer to this guide for more details: Set up a prior payroll for QuickBooks Online Payroll.

Otherwise, you'll have to contact our Payroll Support Team. They'll access your account and create an adjustment to record the old payroll transactions prior to using QuickBooks.

1. Click the (?) Help icon in the upper right-hand corner of the Dashboard.
2. Select Talk to a Human.
3. Enter a short description of your concern and press Enter.
4. Click I still need a human.
5. Select Contact Us to connect with our live support.
