Something in the back of my memory. Did they not announce this to save money and because so many are doing electronic. You had to go to the post office or request it. Not sure maybe someone else remembers more or knows for sure.
I know New York State no longer sends them in the mail, but hadn’t heard about the Feds. The post office used to carry the State forms, but don’t anymore. I had to go to the local library last year to get them. I hate wasting my ink cartridges on tax forms, but I’ll probably end up printing them off the internet.
