How to share TurboTax 2019 with daughter?

I purchased TurboTax Premier 2019 and used a digital download to my laptop. I shared my license code with my daughter so that she could use one of the 5 e-files and the state e-file. When she tried to download the program to her laptop, she got this message:  "This license code has already been associated with an account. Please check that account and look for it in Downloads." How do we download the program to her computer?
