Retirement tax questions

Im sorry, but I dont understand/see what you're talking about.  Am I going to enter this in the Wages and Salaries? If so, I dont see a box to check taxes undetermined.  If im supposed to enter it under Retirement Plans and Social Security, then the questions are a bit different than what you have listed.  There's not a box to check for undetermined  and the question is, Were you under your minimum retirement age when you received the distribution?  Thanks

 

Thanks
