How do I fill out form 9465

[JohnW15]

In TurboTax, go through the File section 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.

Please see the IRS' Instructions for Form 9465 for line-by-line instructions.  You can follow along by looking at Form 9465.
