I have the same problem, only with CA and IA state returns.
Filed the federal to make sure it would be accepted, choosing to efile the state returns later in the efiling window. Federal return was accepted, and the efile window says so, but when I try to efile the state returns I get
E-file requires federal return
To e-file you must also select the federal return.
Click Back to select federal and any other returns you'd like to file.
Only there is no federal return to select any more because it has been accepted.
