Welcome to the Community, awarren.

I'd be glad to help walk you through in checking the options to print paychecks in QuickBooks Online.

You can go to Payroll Settings to check the paycheck option before printing them in QuickBooks Online.

Here's how: 

1. Click the Gear icon at the upper right corner and choose Payroll Settings.
2. Go to Preferences and click Paycheck Printing Settings.
3. Make sure that the Preprinted check stock is selected.
4. Hit OK.

This article is a good reference: https://community.intuit.com/articles/1762595-set-up-and-print-payroll-paychecks-and-pay-stubs.

You'll see some screenshots below outlining the steps above.

I'll be around here in the Community if you need more help with printing paychecks in QuickBooks. Have a wonderful day!
