Thanks for the reply ( and query).
No I saw the duplicate entries before I started preparing the amended tax return. No the "data transmitted to the IRS" didn't create these duplicates. I must have entered this when beginning my tax filing ( by mistake). I had to enter about 3 or 4 numbers into the tax form ( that was issued by a bank). Every entry was the same ( as in the other form that I had entered). So Turbo Tax should have asked me to check on this when "reviewing" my tax returns....
