After you file

When you click fix it now, it doesn't let you fix it. The only option you get is to resubmit. I will reply with some pictures

This appears after hitting 'fix my return'

After clicking 'revisit'

Hitting 'continue' (the only available button) brings you here

You are then made to just resubmit it, without changing anything. Which I have done about 5 times now.
