After setting up the employer contribution item, adding it to your employee's profile, and running payroll, QuickBooks will include them in your taxes, Priority73. I'll provide more details about this below.
Company contributions are usually exempt from taxes but are reported on some payroll tax forms. Based on your description, I can tell that you've set it up accordingly in your QuickBooks account.
Moreover, our payroll services don’t automatically report employer-sponsored health insurance on W-2s. Depending on your payroll service, you may need to contact our Payroll Care team to have it added or take extra steps when filing the form. To learn more about this, please see this article: Report employer health insurance on W-2s.
Also, I've included this article to help you prepare your tax forms in QBDT Payroll: Year-end checklist for QuickBooks Desktop Payroll.
