Our company has a SEP Plan that only the company contributes to. I need to check "Retirment Plan" in Box 13 of the W2

Thanks for reaching out to the Community, @TGAC. I'm here to provide information about editing W-2 forms in QuickBooks Online (QBO).

In QBO, you need to set the retirement plan in your employee profile first to show it on the W-2.

You can also take a look at this article for more details about the retirement plan deductions/contributions in QBO.

On top of that, I'd recommend reaching out to our QuickBooks Payroll Support Team. They can assist you, and they have the tools to make corrections to your W2 forms.

Here’s how to get in touch with our representatives:

1. Log in to your QuickBooks Online account.
2. Click the ? Help button at the top right corner.
3. Go to the Search tab, then select Contact Us.
4. Type in "W2 payroll forms" as your concern, then click Continue.
5. Choose a way to connect with us: Ask the community, Start a chat or Get a callback.

Additionally, if you want to view and print your W-2 forms and send some copies to your employees, you can visit this article: Print your W-2 and W-3 forms.

Always know that you can get back to me anytime if you have further questions about this. I'm just a few clicks away. Keep safe and have a good one!
