my federal return transmitted, but my state return did not?

(Assuming you e-filed them together, at the same time...)

The state forms do not "Transmit" until the IRS "Accepts" the Federal filing.

That's a separate step in the process... first the Federal file is "Transmitted" to the IRS....then the IRS computers do a cursory check of the Federal data, which can take from ~15min-to-48 hrs (usually), and then the IRS either "Accepts" or "Rejects" the Federal filing.  IF the Federal is "accepted" , only then is your state tax file transmitted to the state.....but not if the IRS rejects the Federal filing.

Why?  IF the Feds "Reject", then something is apparently wrong, and the state doesn't really want to see anything until the Fed part is fully correct.

Will the state filing be considered to be late if the IRS takes too long?  Usually not a problem...your initial submission date/time is a part of the data being filed...so long as that was before the deadline, then no problem.
