We are trying to e-file a California single member LLC and when we try sending it we get an error diagnostic message that says we have critical federal diagnostics (there is only one partner on a partnership return) and it can't send it because a federal return will be attached to our state return.  We have unchecked federal and there should be no need to attach a federal copy.  We know there is only one partner because it is a single member LLC.  Has anyone else ran into this problem?
