I have the desktop version of TurboTax Premier. How do I delete a return? I have several versions and it is confusing

You can delete the return from the folder where it is stored on your computer.  Use the link below for assistance.

Another Option:

Also, you can bring each return up then choose to save it with a different file name.  Keep the file name you want for the one tax return you know is the actual return you want to file.  

You will be able to see the file names on each return, which will allow you to always know which file you are looking at.
