How do I pay directly to IRS instead of via TurboTax

TurboTax Desktop user.

 

I calculated my return and determined that I owe IRS some tax. I want to pay tax directly with IRS instead of via Turbo (processing fees for direct payments are cheaper).

 

When trying to e-file, TurboTax does not let me e-File, without selecting the payment types? How can I pay direct and e-file?
