"Line 16 Rents, Royalties, Partnerships, etc.
From federal Schedule 1, line 5, enter the amount reported on Schedule E earned or received while an Idaho resident or part-year resident or related to Idaho business or property. Report passive activity losses from Idaho activities that are “Allowed” losses from federal Form 8582 and corresponding worksheets."

Does that help?

Not really...it does not answer the the fundamental issue of how to handle a loss going forward as it relates to Idaho

You mentioned a Federal Form. I copied an example where Idaho shows the use is the Federal Form. You mentioned ProSeries tax year 2021. Intuit added a worksheet to the program for Federal Form 8582. Idaho doesn't seem to have a State Form 8582.

Did you start Idaho from having Fed for this client? I found you a help article that might be the explanation for you:

thank you for providing assistance to this matter.

That is the strange part of this issue, I contacted the Idaho people and they indicated that they still use "Idaho form 8582"  so there seems to be an inconsistency between how Intuit and Idaho deal with unallowed passive losses.  I will just keep digging

thank you

This is all I have from 2021:

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).
