Illinois portion of adjustments to income

[hd1998]

I lived part year in one state and part year in Illinois. Filing self employment income.

When filling out the Illinois portion, I get the message (Allocate all or a portion of the deductions reported on your federal return to Illinois based on the length of your residency or the source of the deduction.)

Do I allocate a portion of ALL the deductions on my federal return? Just the self employment tax deduction? Just the standard deduction that I took? It does not specify which deductions I should be using to calculate the illinois portion.

all income and deductions must be prorated between Illinois and your other state. 

see the Illinois 2024 schedule  NR

see the instructions

basically all items in column A are allocated between Illinois (enter amount in column B) and non Illinois.
