Hi there, @laurammenke33.
Thank you for joining on this thread. Allow me to help share some information about the error message you received when uploading the file.
In QuickBooks, we can only generate a .txt file for state W-2. If it's producing an error when uploading to the agency site, I'd suggest contacting the agency first. It could be that your state website requires a different format, so it'd be best to ask for assistance from them.
Let me know how it goes. I'll be on the lookout if you have further questions about your W-2. Have a good one.
