Retirement tax questions

i have this issue every year and Turbotax has never fixed it. one fix is t change the 1099r box 2a to ZERO. With so many people doing back door roths every year i am not sure how both answers think it is taxable!! you contribute on day 1 and "convert" (it seems TT thinks that is recharacterizing) the next day. that would never be a taxable event. i am so disappointed in TT!
