Thanks for coming back and sharing some clarifying questions about this matter, @beckibrack. Let me guide you on how to populate the medical premiums and deductions in Box 12 Code DD.

You can select the tax tracking type for both contributions and deductions. However, if you're facing an issue with deductions, you'll need to resolve it by creating a new deduction payroll item with the correct tax tracking type. After this, update the employee's payroll. 

Next, to determine the YTD (year-to-date) amount of the incorrect payroll item for each employee, you can run a payroll summary report of the current calendar year. Once you have the YTD amount, you can correct the class item in the employee's paychecks. You can refer to Step 3 of the article to know how to correct them.

Once done, you can check the Box 12 Code DD in the W-2 Forms.

Additionally, you can submit your W-2 Forms to the Federal and state agencies electronically with QuickBooks. 

You can also print the forms if you want to send a paper copy to your employees.

You're always welcome to get back in the thread for other questions and concerns about managing your contributions and deductions in the W-2 Forms. Our team is available and ready to assist you. Have a great day and stay safe!
