My withdrawal is not taxable. I am over 591/2 & the account has been open more than 5 years. What I do not understand is understand is what to enter into TurboTax when I am asked my prior contributions (over 40 years including transfers of my money from other financial institutions IRAs & conversions from my traditional IRA). I don't know that number & neither does Vanguard where I have my Roth IRA. What happens, if I leave it blank. Vanguard is stating that the money is non-taxable on my 1099.
