I'm having the same issue as well. I chatted with a Live agent and was advised to try again on 2/11/2022 as it should be fixed by then.
But really this should be a simple True/false check in the code on whether you have dependents or not. I'm surprised this issue wasn't fixed within hours of it being reported. A bit disappointed that such a glaring issue made it through. I've always used Turbo Tax, but may have to switch to a different company to file taxes in the future
