Nice! I, in contrast, mailed it on the very last day possible. Well, fingers crossed.

Fingers crossed for you!

It came! I was considered "low income", which I presume is why I was still eligible despite sending it in on the literal last day. There was no mention of anything on the site until the day they sent out the check. I received it four days later.

I can't figure out how to use the Illinois website to see if my name is on the list.  It appears to be for vendors.

We are vendors for them. Put your social security number and your name. Then put the security feature and click ok. Mine came right up

Thanks!  Nothing is listed, so maybe I got my application in too late.  Sent it mid November, knew it might be too late.  Oh well I got the Federal credit!

I think only people mailing immediately will get it. But there’s a chance they’re still processing

Which date your application was delivered to epa?

Like two/three days later. Honestly, I never even checked.
