Thanks for the update, @info1567. I appreciate you for getting back to this thread.

Allow me to chime in and share additional details about submitting your W2s with QuickBooks Online (QBO).

As I've checked my resources here, I've seen cases relating to your concern that have worked on their end. To help you resolve the issue, consider editing the address into one complete line or splitting them to allow the numbers and letters to appear on the first line.

Additionally, we can check and follow these possible alternatives that could help resolve the error received:

• Ensure to spell out the main filing address
• Remove middle initials

This way, we can ensure all addresses are verified and in the correct format.

If the issue persists, I suggest contacting our Customer Support Team again to guide you with the processes and can pull up your account in a secured environment setting. 

Furthermore, you can check out this article to guide you with the time schedules in filing your W2 forms: File your W2 forms. Thus, it provides you with details about submitting them electronically or manually.

Keep us posted if you require additional assistance with filing your W2 forms. We'll be right here to assist you. Stay safe!
