Unable to efile state after efiling the federal

There is a bug in Turbo Tax windows version. I efiled my federal and it was accepted. Then I tried to efile my state, but the software kept telling me to efile my federal together. I was lead back to the page with "federal was transmitted" message. What a technical failure! So the state efile for $25 is a one-time deal? I don't even consider that as a good deal.
