It's good to see you again, johnfilas.

Let me help create a check to your SEP IRA provider in QuickBooks Desktop.

After creating the employee's paycheck, QuickBooks allows you to record a check through the Pay Liabilities window. To do so, you can follow these steps:

1. Go to Employees and choose Payroll Center.
2. Select the Pay Liabilities tab.
3. In the Other Activities section, click on the Create Custom Payments link.
4. Set the date range and click on OK.
5. Mark to select the SEP IRA check and click on the Create button.
6. Then, you can either print the check or click on Save & Close.

For your visual reference, please see attached screenshots.

You can also check this article for more information: Set up and pay scheduled or custom (unscheduled) liabilities.

From there, you'll be able to create a check for the SEP IRA provider.

Please let me know how things go once you've tried these steps. I'll be here to keep helping. Take care.
