You're correct that boxes 12DD and 12FF in QuickBooks Online (QBO) can be edited to reflect the health plan amount on W-2 forms, Finsecmnbc.
However, know that the code E for box 12 isn't editable and is automatically generated by QBO when you've set up a 403 retirement plan in your employees' information and are running payroll with it. To set up this retirement plan, you can follow the steps below:
- Go to the Payroll page of your QBO account.
- Navigate to the Employees section, then choose your employee.
- In Deductions & contributions, click Edit.
- Select + Add deduction/contribution.
- Select Retirement Plans in the Deduction/contribution type ▼dropdown.
- For Type, select the 403b retirement plan.
- Enter the name of the provider or plan in the Description field (this will appear on your paycheck).
- Complete the remaining fields.
- Once done, click Save.

Meanwhile, kindly note that the W-2 forms can be available starting January 1, 2026.
