I'll assume you used Online TurboTax to file your Federal return. Did you efile your Federal return, and if so, has it been accepted? If you recently efiled the Federal return by itself, you can't efile the state return until the Federal return has first been accepted. Log into your Online TurboTax account where you prepared the Federal return. You should be able to tell at the Tax Home if the Federal return was accepted.
If accepted, then you need to open the interview back up to prepare the state tax return. To do that, while you are at the Tax Home scroll down a bit and look for a link "Add a State." That will open the return interview back up. Then go to the STATE taxes tab and begin the state interview. At the end of the state interview, go through the REVIEW. If all is in order, proceed to the FILE section, and go through the screens all the way to the end to click on a big orange button "Transmit Return Now."

NOTE: When you open your return back up, do not make changes in your Federal return since it's already been filed (assuming it was accepted). If you later have to amend the Federal return for any reason, it has to start off exactly as filed.
