Can I still do my 2023 Illinois taxes on line! I haven't filed them for 2023

[BlondieCat]

I e-filed my 2023 Federal tax return but never did my Illinois state taxes! can I still file my 2023 Illinois state tax return online with turbotax?

No.   Online TurboTax is only for 2024 returns.  You cannot use online for a past year return.

You could use the desktop software to prepare a 2023 state return on a full PC or Mac, or you could try going on the IL site to get the forms to prepare and mail in.    A 2023 return can only be filed by mail.

If you already paid for your online software you can ask customer support for a download of the desktop software.

They are available from 5 a.m. to 9p.m. Pacific time daily
