It's there...it's tricky.  On main INFO WORKSHEET where you indicate which state(s) you are going to eFile there is now an option in the dop down menu for Ohio SD100.  Then when you get to SD return it won't populate until you enter that taxpayer has lived in district 1/1/23-12/31/23 or whatever dates.  Someone made this much more complicated this year for some reason but now that I found it I'm on a roll.
