I know I did it. It was a new feature this year in Turbotax in some states. I'm in NY state. I know it worked (at first) because it did indeed make my first estimated tax payment.
Turns out, though, that that was the only payment it made. I just found out what I would have to do to cancel future payments, but it was through NY state, not Turbotax, and when I went to do it, the remaining three payments weren't there.
