I know this has come up in the past, but it's been a while since I've seen anyone ask about it. Did you receive a survey and magazine offer when you finished filing online? Was it a year or two ago or longer? I believe that's handled by a third-party marketing company.
Phone TurboTax Support. They may be able to tell you who the third-party company is that does that magazine marketing.
If you have any trouble getting info from Support, report back, and I'll see if a Moderator can help find any info.
Hours are currently 5AM-5PM Pacific (8AM-8PM Eastern) Monday-Friday.
