I need to change my 9465 how can i do this?

[LukeG]

You can edit form 9465 as long as you haven't filed yet.

To get to Form 9465, go through the File section of Turbo Tax until you reach the screen How would you like to pay your federal taxes? (You won't see this screen if you owe $0 or are getting a refund.)

Then, select I want to request an installment plan, Continue, and follow the onscreen instructions.
