Thanks for the clear and pointwise response @Hal_Al . I appreciate it.
Regarding the tear-off part: I got that I can send the tear-off part. However, in the W2-c I got the tear-off part doesn't seem self-informatory. I believe sending the full form won't be an issue? I am concerned about the case when they have an automated process and the full form messes it up.
Okay. I will not mail the W2-c with my IL return. I have not yet filled IL, so no question of amendment there. But I got it that there is no need to include the W2-c with it. Right?
Please feel free to ask for any clarification.
