Final answer.. While those fields on the Indiana State for are "editable", the are NOT intended for user entry. This was proven by going back to my FED form .. unchecking the "pay all" check box .. and then going back to the state and seeing the other 2/3s value on that form.
While in hindsight that may be clear.. it was not when I posted the question.. and some replies led me down the incorrect path.
Thanks for all the help.. Much appreciated.
