I am in the same boat. It is trying to charge me $128 as well. I meet all the terms of the offer. I started on the mobile app, I didn't file with Turbo Tax last year, I used "do it yourself" mode, and I went to file through the mobile app as well.
I called support and the agent knew nothing about the offer. She talked to someone behind the scenes extensively, tried applying a service code that didn't work. Then 52 minutes later she "transferred" me to another agent, but also closed my ticket at the same time, so that agent could not help and made me start all over with a new call.
Also it looks like they have shifted the deadline to 2/28 now.
