Congrats on making your first post here in the Community. Allow me to point you in the right direction so you can print a check through your QuickBooks Online account.
All you need to do is a few easy steps. I can walk you through the process. Here's how:
QuickBooks Online Payroll
Go to the Payroll tab on the left-hand menu bar.
Hit the Employees portion of the page.
Choose the Paycheck List in the "My Payroll" section.
Tap Print after you select the paychecks you'd like to print.
