Thanks for reaching out, @Thor1. Happy to provide some insight here.
At the moment, QuickBooks Online doesn't support the ability to populate the 83b election. If one of your employees has elected for this, you'll need to file this outside of QuickBooks Online at the moment. I've forwarded this idea to our Product Development Team for further review, as I think it'd be beneficial to you and other businesses.
Let me know if you have any other questions. I'm here to help. Have a good one!
