Neither Intuit nor TurboTax would send an email
with that kind of information in it. Check who the email came from. If it’s
from the CRA, you can contact them or check your My Account to see what info
was changed. If you are in Canada or the United States, you can call the CRA at
1-800-959-8281. If you are somewhere else you can call 613-940-8495. Here are
more ways to contact the CRA:

If you suspect the email came from a scammer, you
can contact the the Canadian Anti-Fraud Centre (CAFC) at 888-495-8501 or visit
their website: http://www.antifraudcentre-centreantifraude.ca/index-eng.htm
