Hi there, @Vtori67.

Importing the payroll details from QuickBooks Desktop into QuickBooks Online is currently unavailable. That's why you're unable to find the past pay stub.

I'd like to let you know that paychecks are moved to regular checks to keep your financial reports accurate. To know which data you can transfer from QBDT to QBO, please refer to this article: Learn how features and data move from QuickBooks Online to QuickBooks Desktop.

I'd recommend checking the Payroll Summary report to get a complete view of your total payroll wages, taxes, deductions, contributions, and payroll history.

Here's how:

1. Click the Reports menu on the left panel.
2. Scroll down to the Payroll section and select Payroll Summary by Employee.
3. Set a date range and click select Apply.
4. Click Customize to include the wage details.
5. Choose Run report.

Lastly, if you need further guidelines in effectively managing your business using QBO, you can open this article: Help guide for QuickBooks Online. It contains topics about advanced accounting, banking, and payments to name a few.

If there's anything else you need about managing your payroll, just click the reply button. I'm always around to help
