For In 2018 we release a Free version of TurboTax CD/Download, but as it wasn’t popular, it was discontinued and not released for 2019.
For 2019 we used to have TurboTax Free Online, but as we only keep 3 years of TurboTax Online active, all versions of TurboTax Online 2019 are no longer available.
Also please note that for 2021 & 2022 TurboTax Free Online can’t be used for Non-Resident returns.
