Can you still e-file if you fill out a form 9465 for payment installments?

[TomK]

Yes, but only if you haven't filed your tax return yet. 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).
