I received an email from you about a Retirement Seminar for next Wednesday. Was this legit or did I fall for a scam? Thank you.

While your "you" is not any of us in here....There appears to be an upcoming valid session from Intuit/TurboTax about a special Retirement Q&A .

There is an Ask The Experts event next week.  Not really a Seminar, per-se, but somewhat of a Q&A session
