Trying to select the "installment payment plan option" while filing my taxes.

[NancyG]

The IRS will let you pay off your federal tax debt in monthly payments through an installment agreement.

If you haven't filed yet, step through the File section of TurboTax until you reach the screen How do you want to pay your federal taxes? Select the installment payment plan option, click Continue, and follow the onscreen instructions.

If you already filed, or you're unable to find this option in TurboTax, you can apply for a payment plan at the IRS Payment Plans and Installment Agreements web page (make sure you've filed your return before applying through their site)
