Perhaps more info is needed.
I suspect you shouldn't need Other State tax part of the 39R at all.
IF...if your HOR/State of legal residence (SLR) is IDaho? Then your Military W-2 income is not taxable by CA.
Only if you worked a civilian job while off-duty in CA (civilian W-2 or Self-employed work in CA), only then would you need a non-resident CA tax return that would result in CA Non-resident taxes being assessed.
If your HOR/SLR is ID, then you do NOT indicate you moved to CA in the Personal Information section of tax software. As an active duty military person, you are treated as having lived in ID all year, no matter were you are posted or deployed.
