If you do an internet search you will find multiple websites accusing both TurboTax and H&R Block of charging customers for the use of their software when the customer was eligible for free filing.

It is doubtful that the email your friend received was directly from TurboTax.  It most likely was a fishing expedition by some law firm and may well be a scam.

There is a Non-Secure website out there with an address similar to what you posted.  I will not post that website on a public forum.  But a review of the site seems to be fishy since they have phone numbers listed to call but only show numbers like these - (646) ***-**** and (800) ***-****

If your friend thinks he/she was incorrectly charged when they qualified for using a free product, he/she should phone TurboTax Support to see if they will offer any remedy.  I don't know what they will say, since it likely depends on all the circumstances.

If they indeed used a paid product, then that entitles him/her to phone support privilege.

Hours normally 5AM-5PM Pacific (8AM-8PM Eastern) M-F, but are also open today and tomorrow (Sunday) this weekend only.
