Sam190909, TurboTax does not ask that question for distributions from IRAs. It only asks that question for distributions from qualified retirement plans, indicated on the Form 1099-R by the IRA/SEP/SIMPLE box not being marked.
Assuming that this is indeed a distribution from a qualified retirement plan and not from an IRA, a lump-sum distribution is not a series of regular, periodic distributions; you should have answered No to the question that asks about periodic payments.
