Welcome, and thank you for posting about printing checks.
We cannot create or print paychecks in QuickBooks Self-Employed because it does not have a payroll feature. I think you've selected the incorrect product tag in your question. If you use any of our payroll services, please let me know what it is.
On the other hand, you can also look for articles for QuickBooks Self Employed on the main support page.
Feel free to reach back out if you have other questions in mind.
