These should have different codes in box 7 (one with code 1 and the other with code 7). Although TurboTax flags these as possible duplicates despite the differing codes, you should be able to ignore that warning and continue. If TurboTax will not allow you to continue, you could try changing one of the dollar values on one of the Forms 1099-R by $0.01 so that the value still rounds to the same whole dollar amount.
