TurboTax saves tax data and PDF files in the Documents (or My Documents) > TurboTax folder on your PC.
To move the return to your PC's Recycle Bin, go to Documents > TurboTax, select the file, and tap Delete on your keyboard (you can also right-click the file and select Delete). There may be a corresponding PDF file, which you can also delete.
To permanently remove it from your system, delete the file from your Recycle Bin.
