Hello dennisltubbs, 

Welcome to the Community. It's essential you're able to set up online payments in QuickBooks Self-Employed. I'll be happy to point you in the right direction so you can get back to doing what you enjoy. 

I encourage you to check out the following helpful article that shows you how to: 

Set up Payments in QuickBooks Self-Employed (application or apps). The article provides more details on how you can accomplish this on your end. I encourage you to review the article and let me know how you make out. I'll be one message away in case you have other questions. 

Otherwise, I wish you a great rest of the week!
