How do I delete a tax return that was created in TurboTax for Windows?
By default, the TurboTax software saves your tax return files in the My Documents > TurboTax folder.
Simply navigate to My Documents > TurboTax and then delete the tax file by highlighting it and clicking the Delete key (or right-clicking it and choosing Delete).
Tip: The naming convention for tax files is Tax year – Last name – First initial – Type of return, e.g. 2015 Doe J 1040 Individual Tax Return.
Then, to permanently remove the file from your computer, open the Recycle Bin on your desktop, find the tax file, and delete it again.
