IRS Payment Plan Questions

I'm in the last stages of filing 2017 taxes.  My wife and I have a huge tax bill this year due to a withdrawl from my wife's IRA.  $ was used to help us pay cash for our retirement house.  We will be using the payment plan option to pay our taxes, but I want to make sure I understand the mechanism using TurboTax before I file.  I would like to e-file and pay a portion via check and set up the payment plan.  Any insights on the process are helpful.

 

Thanks
