When you buy from Costco or any store it is for the Desktop program. You have to install the program on your computer. Do not use the Online web version where you log into an account. You can not apply the Desktop purchase to the Online version.
I think you only get a CD from Costco. Then after you get the CD you install it or you can download the program from Turbo Tax using the License Code. There will be instructions in the box. Look for it and look for the 14 digit License Code. Keep the License Code handy. And don't throw it away when you are done.
