I have been trying since Friday and I keep getting the exact same error. I spoke to a live chat agent and they were not much help because I tried what they suggested and it did not work for me but here is what I was told . Log out. Log back in. And file your federal only from the drop down menu and try the state taxes later when those forms are ready.
when I went to ask the agent for more directions they left the chat LOL
good luck.
