Get your taxes done using TurboTax

So let me understand this correctly: 

At time of withdrawal they take out 10% and say they are going to wave the other 10%. 

At time of filing taxes they have taken your 10%, say they are waiting the other 10% but tax you 33% over 3 years. 

So you are ultimately paying 43% in tax on the distribution. 

And there is no option to check to break it up into 3 years. There is only 1 box on the website. It says pay full tax or not pay full tax. It changes your refund from $12,000 owed to $1,800 refund by checking or unchecking that box. 

Where is the box to pay 1/3 of the 33% ?
