You can’t transfer info from TurboTax Online into
TurboTax Cd/Download. https://turbotax.community.intuit.ca/replies/2961935
.tax files were only used to NETFILE returns back
before the CRA improved the NETFILE system. Now you no longer need to
download/upload .tax files, TurboTax will send the tax info directly to the CRA
if you file online.
