Normally one can efile the state return by itself after the Federal return has been accepted. But something may be broken. If it is, we'll likely see more users with this issue today.
I myself have seen 3 users in just the last day report that they were unable to efile the state return after their Federal return was accepted. @ VolvoGirl and I were involved in another thread with this issue yesterday, and I also saw a comment in a third thread since.
So this may be a developing issue. @TasnimH2
