(2) 1099-R before & after 591/2

Turbo Tax Deluxe Edition accepts the before 591/2 pension amounts easily, but when entering the after 591/2 1099-R amounts, I’m asked a lot of questions that I have no clue of the correct answer. Then there is a “simplified “ version for an annuity or pension but I feel that that is incorrect, it knocks $3k off my taxable income. I don’t want to be sitting in the IRS’s audit chair later in the year
