If you follow the instructions for opening the form, does it exist in the Fed 1040 for this taxpayer, and did you add Idaho to that taxpayer after confirming it exists for the 1040? As I noted, the ID package has it as a worksheet, not a separate form, apparently (I haven't looked, but that's what is noted).
