Illinois only accepts mailed amended returns. There is no way to e-file the amended Illinois return. TurboTax will have all the instructions needed in the PDF about how to mail in the state return.
To see the completed returns in TurboTax Online, you will need to download the PDF.
To get your 2020 Form 1040 download, follow these steps:
