I just efiled a federal return and but the state return in the EF Center still says "Return marked for EF"

Sounds like you didn't transmit the state with it.

Did you mark the State to be e-filed on the information worksheet? I had one that did that and I found that the e-file state box was blank even though it was a long-term client transferred from the prior year Proseries.
