This is the link you can download our TurboTax Download software when you have already purchased it. Choose the version you bought then use your license code: https://turbotax.intuit.ca/tax/software/install
You may wish to do a search on your computer before trying to download the software again. It may have gone to a different folder. You may also want to delete anything that may have been downloaded already so a partial file doesn't cause an issue with the new download.
Thank you for choosing TurboTax.
