Illinois taxes for Iowa resident calculated incorrectly

[anonymous64356]

Hello. I work in Illinois while I am a resident of Iowa. When I filed my 2020 tax return, I did not get a refund on taxes withheld by Illinois, even though I am supposed to as an Iowa resident. On my Schedule NR, my income from Illinois in row 5 column B was listed as all of my income from Illinois, even though that number should have been 0, as is shown in the instructions for this form on page 7: https://www2.illinois.gov/rev/forms/incometax/Documents/2020/individual/il-1040-schedule-nr-instr.pd...

As far as I can tell, this glitch is still in this year's version of TurboTax. Can I get any compensation for this? Thank you in advance.

You must go back to the Illinois return and allocate the Illinois income as zero.  (See below)

Any wages or salary made by an Iowa resident working in Illinois is taxable only to Iowa and not to Illinois.
