I am having this exact same issue. I was able to file my Q1 DE9C with no problem but now QB won't let me. This is a very similar issue to the W-2 issue everyone was having at the beginning of the year however the workaround for that will not work for this. As for manually filing my DE9C info onto the CA EDD website, does QB even offer a way to export in an XML format or any other format that the EDD accepts, unless I'm missing something...
