Nobody here can answer how long the state will take - only the state knows that.
Since claiming disabled requires a doctors certification of permanently and totally disabled and can request the letter at any time (and often do) - it is advised that you obtain such a letter prior to filing.
(Many taxpayers that make a disabled claim file by mail and attach the certification letter to their mailed tax return to head off delays even thought it is not required to do so.)
