Get your taxes done using TurboTax

What if I downloaded the original 1099 over the internet, and before I file the return, I get a notice that there is a CORRECTED 1099 - if I download the CORRECTED 1099, is TurboTax smart enough to replace the original, or will it just add the CORRECTED version forcing me to manually delete the original 1099 (and how would I do that)?
