Hi @andriarad,

Welcome aboard to the Community. Allow me to chime in and share some information about how you can set up the Employer Match additional item in QuickBooks.

You can enter Employer Match for the 401(k) plan as a company contribution in the system. If you're using the Enhanced version of payroll, you can set up the item through the Payroll settings section.

Here's how:

1. Click the Gear icon in the upper-right corner, then select Payroll Settings.
2. Under Payroll, select Deductions / Contributions.
3. Select Add a New Deduction/Contribution. 
4. For Category, select Retirement Plans.
5. For Type, select the applicable retirement plan.
6. Enter the name of the provider or plan.
7. Hit Ok.

If you're using a different payroll subscription, you'll need to contact Payroll Support  for assistance.

For more information, as well as how to assign a retirement plan deduction and company contribution, I recommend the following article: Set up or change a retirement plan.

Drop me a comment below if you have any other questions related to adding payroll items. I'll be happy to help you some more.
