I heard that people would be getting refunded for having to pay for TurboTax's services when they should have been free. Does anyone know anything about that?

Certain users who started in the Free Edition and ended up in a paid version will receive a check for about $30 for each tax year between 2016, 2017 and 2018 if their income was $34,000 or less.   You do not "sign up."   If you are one of the affected users you will automatically get the payment.   We do not know how soon the payments will be sent.

A notice and a check will be sent to you if you are a Covered Consumer as defined in the settlement agreement.

Here is the definition of "Covered Consumer."

"Covered Consumer" means any individual, or individuals if a joint return was filed, who in Tax Years 2016, 2017, or 2018 was (1) eligible to use an Intuit IRS Free File Product; (2) began his or her tax returns using a TurboTax Free Edition Product; (3) was informed that he or she was ineligible to use a TurboTax Free Edition Product; (4) subsequently paid to use a TurboTax Paid Product, and (5) had not used the Intuit IRS Free File Product in a previous tax year.
