How can I share my desktop TurboTax license key with my daughters so that they can do 2020 tax returns?

[Julie30]

I purchased the desktop version of Turbotax and installed it on my laptop.  With my permission, Daughter #1 downloaded using the license key and it prompted for my Turbotax account, which i gave her.  Daughter #2 is now trying to download using the license key, and it also prompted her for my Turbotax account, which i gave her.  It says that the account is in use, and she is able to see her sister's tax info, and not do her own?  My questions are:  1)  why are we able to see Daughter #1's return info?  2)  How can Daughter #2 download the software using my license key and do her own taxes on her laptop?

While you are able to prepare and file multiple returns with your software, each person must create his/her own user ID and password.
