Get your taxes done using TurboTax

I purchased a copy of TurboTax Premier 2019 and installed into my computer.  Now, I want to give a copy of the software to my friend.  When my friend tried to download it to her computer, a message came telling her the code she put in is being used by someone.  So, she needs to look into that account and go to  download.  I find my download but I don't know what to do to get her my download.  Can I copy the download to her?  Thanks.
