Illinois where to find AGI for 2022 - part time resident

[clemsongrad]

To eFile Illinois tax returns as part time resident, I need to find out AGI from 2022 return.

The Turbotax tool tip shows the following:

I am signing this Tax Return Signature/Consent to Disclosure by entering the following information.

If you know your Illinois 2022 Adjusted Gross Income (AGI) enter it here:

Use line 1 from your 2022 Illinois Form IL-1040 Note: If the prior year AGI was adjusted due to an amendment or correction by the taxpayer or IDOR, the most recent AGI on file should be used.

Is this correct??  Is this a typo from Turbotax?  Should this be "Line 9".  Or is this correct that it is Line1 or Line11?  Can you please advice.

Line 1 of your Illinois IL-1040 reports your federal adjusted gross income.   This is also Line 11 of your federal tax return.   You may reference either of those to find the correct number to use for filing your Illinois tax return.  

The language is a bit unclear as Illinois also has a "base income", which is Line 9 of the Illinois return - but the correct number to use is the federal adjusted gross income, found using either method listed above.
