I know where I am and where I posted, thanks. This is the only thread that I could find that addresses the issue of having a negative AGI on the 2020 "Where's My Payment Tool" not being accepted and returning an error that had any reply/response as the threads in the general discussion and there was an active thread here, so I posted asking if a solution was found. So yes. I am in the same exact boat as the OP. 

Nothing in any of the IRS documentation that I could find even addresses this issue as well as the TACs being closed so there's no official way to reach out. By replying and asking if there was a solution found I am doing exactly what you suggest in "watching the news for when this get resolved" and yes, I've been through the TTCommunity discussions, the few mentions are all dead posts.

So I ask what did your post add to any aspect of the question?
