Does the code G Form 1099-R have a zero in box 2a? Is it blank?
Is box 2b Taxable amount not determined marked?
Make sure that you selected code G in only one of TurboTax's box 7 drop-down boxes and left the other one blank.
Make sure that you did not inadvertently mark the IRA/SEP/SIMPLE box on this form in TurboTax.
