A state's portion of adjustments to income
TT says: Allocate all or a portion of the deductions reported on your federal return to IL based on the length of your residency or the source of the deduction.
I ask: Where on the federal return does one find the deduction information?
TT says: Enter the amount that applies to the time you were an IL resident or to your activities in IL.
I say: I was not an IL resident during this tax year but did work in the state.
