I found online that Illinois began accepting amended returns electronically starting in 2020, but I don't see Illinois listed in the ProSeries dropdown menu for filing an amended return. Is this information incorrect, or is e-filing for the IL-1040-X not yet available? I checked the Illinois Department of Revenue website and it mentions a mailing address but it doesn’t specifically state that amended returns cannot be e-filed.

If you check the ProSeries forms release date page, you can see that e-filing of the form isn't supported.

The form is in Pro Series, but you have to mail in, or efile on the states web site.
