Hi there, tiredofbadanswers.
Currently, you are not able to edit or add health insurance to owners to Box 1.
However, I suggest contacting our QuickBooks Support Team. They have the tools to set up your account to add the item to the specific box.
Here's how to contact them:
1. Open your QuickBooks Account.
2. At the top right, click the Help icon.
3. Click Contact Us.
4. Under What can we help you with?, enter any concerns.
5. Click Let's Talk.
6. You'll be routed into the Choose a way to connect with us page.
7. Select how you want to contact them and fill in the information.
Please check this article how QuickBooks Online populates the boxes on the IRS Form W-2: W2 form boxes explained.
Please know that you're always welcome to post if you have any other concerns. Wishing you and your business continued success.
