Turbotax rejects me at payment screen?

I live overseas and do not have taxes in USA due to this. I file my taxes every year, though, just in case. Well, I run into the same issue except this time there is a bit extra. I fixed the common issue most expats have when filing online, but it still rejects me. It says everything is good and there is nothing to review except when I go to pay I am rejected, but nothing tells me why.
