Get your taxes done using TurboTax

@Anonymous I was browsing in my own TurboTax account earlier this week and came across a different way to opt out of emails, etc.  

Log into your TT account.  On the left side of the screen, you should see your "Intuit Account" near the bottom left.  Once you click on that, you should see the option of personalizing your "Communications".  Maybe this will help.  Screenshot below.
