The Download is the same as the CD. They are both the Desktop installed program. You need a full Windows or Mac computer to install it on. Hopefully you picked the right download Windows or Mac. All the CD/Download Desktop programs have the same forms so you can use any version. You do get more help in Premier for Schedule F.

DESKTOP vs ONLINE
The CD/Download Desktop you buy and install the program on a full Windows or Mac computer (a desktop or laptop), which can do unlimited returns. The returns are only saved on your computer and can not be accessed from anywhere else. And not saved at Turbo Tax. So Be sure to save Frequently and make backups. You get 5 federal efile for free. In Deluxe and above you get 1 state PROGRAM download to prepare unlimited state returns (in that state). Each state return including the first one is $20 early or $25 to efile or you can print and mail the state for free. And since you bought it at COSTCO you get a $10 rebate which will automatically be applied to the state efile fee or any other service you might add.
The Online web version is only good for one account and one return. But you can use the same email address for 5 accounts. You can log in and access your return from any computer. You only can see the forms after you pay and download the pdf. And you might need to upgrade to a higher version to enter different kinds of income. And you can add LIVE service or Full Service for expert help. In Online the fees are to prepare the federal and state returns (State is a separate charge) whether you efile or print and mail. Efiling is free and included.
