First, technically, the license says you can install the software on multiple computers that you own, and you can prepare as many returns as you want (as long as you don't charge a fee), and e-file the first 5. The license does not say you can give a copy to a friend or relative to install on their computer.
Assuming you are going to violate the license, you need to locate the installer file (an .EXE for windows and a .DMG for Mac) and get that file to your daughter. Although you can't generally email attachments that large, there are several file transfer services that can be used to share large files, some are free and some are subscription, or you could load the installer file on some type of physical media and mail it to your daughter.
