Hi there, @mmadrid. 

Thank you for reaching out to the Community. The option to create/print check is not available in QuickBooks Self-Employed. You can only send invoice and track the transactions.   

Here's how to send an invoice: 

1. Go to Invoices, then click Create invoice. 
2. Fill up the information field, and enter the client Email. 
3. Click Add to invoice. 
4. Hit Send invoice. 

Once done, your client will receive a notification through email. If any changes are made to the Invoice (including when it’s paid), anyone who received the Invoice will be able to open it with their initial email and see the changes reflected automatically.

You can check this article for more details and workflow about QuickBooks Self-Employed: QuickBooks Self-Employed Overview. 

Let me know if you need more assistance with this. I'll be around to further help you. Have a great day!
