Why is the company paid insurance now showing on checks

Let me help you get this matter sorted out, @mmartindale. This way, you're able to identify the other pay/contributions amount on your check stubs in QuickBooks Online (QBO).

You can get a closer look at your business's finances and employees' accounts by pulling up a payroll report. With this, I'd recommend running the Payroll Details report. This will give you  detailed info on your employee's payroll. To do this, here's how:

1. Go to the Reports menu.
2. Enter Payroll on the search field and select Payroll Details.
3. Filter the appropriate date, then click Apply.
4. Review the amounts under the Other pay column. 

To see the complete list of available payroll reports, you can refer to this article: Run payroll reports.

Keep me posted if you have other payroll concerns and managing paystubs in QBO. Don't hesitate to drop a comment below, and I'll gladly help. Take care, and I wish you continued success, @mmartindale.
