What does the rejection code IL1040-8100-1 mean? I checked my state return and it was all correct.

I don’t understand what is wrong with my Illinois state tax on 1040-8100-1

Please check your prior year's AGI or your driver's license expiration date and try again.  If this does not resolve the issue, please reach back out here.  

How do I find last year's AGI?

Here's what I did after my return was rejected; even though all my info was correct.

After I went back through the third time to "fix" my return, when asked I ticked the option saying something like "I've never filed in Illinois before but I do have my Illinois DL/ID."

I entered the DL/ID info (all caps) including weight number listed on my ID card, and submitted my return again. My return was accepted in a couple hours. No idea why, but this worked (even though I've e-filed for 2yrs with Turbotax). Meh.

Anyway, I hope this helps someone else 😉

This is not helping, any other updates? if I pay for upgraded service would they be able to solve it for past to current returns?

@TDiamond You are posting to an old thread.  There is nothing you can do to e-file a past year tax return.  E-filing is closed for all tax years except 2022.  If you have past tax returns that have not yet been filed, the only way to file them is by mail.   Print, sign and date them in ink and mail them.  Mail each year in its own separate envelope or you risk that one or more will be overlooked by the human that opens the mail.

Please explain clearly what the issue is for your 2022 return.  We may be able to help with that one.

1.  Make sure you look at your prior year IL-1040 (not Federal 1040), line 11 and take note of that number.

2.  Make sure your prior year IL-1040 was e-filed or if it was printed, make sure it was mailed in that tax year for IRS to process it.  

If either statement in line 2 above is true, then you will use the IL-1040, line 11 number as your IL AGI.

If either statement in line 2 above is false and there is a chance IL never received and processed that year's return, then zero will be your AGI for the prior year.

To enter the IL AGI in your online TurboTax screen, go to the FILE section of your return which is the last section of the process.  Just as there is a place to enter your Federal AGI, there will be a place to enter the IL AGI.
