We can tell you how to start a second desktop return, but first something needs to be cleared up.
Underneath your question there is a tag that says "Online TurboTax." Please confirm what product you are in.
Online TurboTax requires a browser and has its navigation as tabs in the left column. Desktop TurboTax does not need a browser during preparation, and the navigation tabs are horizontal across the top.
Did you actually install the software on your computer and used the desktop version for the first return, or did you end up in Online TurboTax by mistake?
