How do I cancel my admend taxes return after it has already been completed by TurboTax

[Mike9241]

if you filed it. it's too late.  if not, you would have to remove all the changes you made to the original return. in any event the original return is now permanently gone. what's left is an amended return with no changes. 

Turbotax did not complete your amended return. You did by selecting amended return and then making changes
