I have already downloaded 1099 B from my financial Institution but there is corrected 1099 B form available. Question: how I can overwrite existing 1099 B with new one?

I cannot be more specific!!

You should delete the first entered 1099 B and import or enter the corrected 1099 B. 

Go into Forms Mode (top right) and click the 1099-B Wks and scroll down on that form and click delete
