TT cracked down on the rules this year. The license code can be used on computers owned by you---it cannot be given out to other people to use on random computers that you do not own. Any download will be linked to your online account. That does not mean, however, that your daughter can see your information. She cannot see your tax return. You can allow your daughter to use your computer---or a computer owned by you--- to prepare her return and she will not see your private information or tax return.
