trying to efile w-2 copy A and get msg Error submitting filing electronically. Error reason:documentsData with an invalid value of null

Thank you for reaching out to the Community, @ibranum.

Let us do some troubleshooting steps if you are unable to file W-2 copy A in QuickBooks Online Payroll (QBOP) to determine if the issue is related to your browser.

To begin, please open an incognito window. This will prevent your browsing history from being saved. You can use the following keyboard shortcuts based on the type of browser you are using:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If the private browsing session works, you can clear the browser's cache to improve the program's performance. You can also use other supported, up-to-date browsers as an alternative which will provide the best and most secure experience with QuickBooks.

I'll be adding these articles to help you manage your payroll:

• Year-end checklist for QuickBooks Online Payroll
• Set up and manage payroll schedules

Please let me know how the troubleshooting steps go. I want to ensure this is taken care of. If you have any other questions about QuickBooks, please let me know. I'll be here to assist you.

Thank you - I use Google Chrome although I tried Edge too. I did the incognito window and still get the same msg

I also have been trying to efile my w2 but it will not let me change my filing method from paper to efile.   I use QB desktop pro 2021.  I’ve called intuit and they say this has been a reported problem and a fix should be done in 2-7 days.
