Earlier I had the french version of Turbo taxe and now I have the english version...what happen? How can I get the french version back and not loose the changes I made?

If you are using the online version of TurboTax, you can sign in either French or English.  No worries you will not lose anything.

Log out of English TurboTax and log in on French TurboImpôt here: https://turboimpot.intuit.ca/logiciels-impot/index.jsp
