Thank you for reaching out and keeping us updated on the situation, Elaine. Ensuring you can submit your W2 file is our goal and I'm here to share how you can achieve this.

When you create a W2 in QuickBooks Desktop, QuickBooks will generate it as a .txt file.

Since you've already performed the troubleshooting provided by my colleague in your initial post, I recommend contacting the Maryland tax agencies directly to ensure that the file meets all their specific format and submissions. They can provide the most accurate advice on how to proceed and help identify if there are any adjustments needed in the file.

Moreover, you can check out this article to learn how to view your payroll tax payments and forms: View your previously filed tax forms and payments.

If you need any help in liaising with the tax agency or understanding their guidelines, please don't hesitate to let me know. I am here to assist you throughout the process and ensure this gets resolved smoothly.
