Go through the screens in the REVIEW section, and see if it tells you why  you are not yet able to efile the state return.

Normally, the Federal and State returns can be efiled at the same time.   However, if the Federal return is efiled first separately, then the State return cannot be efiled until the Federal return has been accepted.

The Federal Return has already been accepted.  In fact, the refund has already been received.  The message tells me that the federal return has to be e-filed before the state return can be filed.  So, for whatever reason the system doesn't seem to know that the federal return has been accepted and filed.

So here's what ultimately happened.  Very strange.  When I went back into the program, it had created another "return".  When I opened that one, it seemed then to realize that federal had been transmitted and finally let me send state as well.  VERY CONFUSING!

Glad you got it worked out.  I think you have to update your return with the filing status so it knows federal was Accepted.  

For the Desktop program you have to check the filing status inside the program.  Open your return and go up to menu item

File > Electronic Filing > Check Electronic Filing Status

Then save your return, close it and reopen it.
