checked with e*trade, they have mentioned that, it is known issue with Turbo tax software.
Turbo tax can't handle large number of transactions download.
As some one suggested earlier, Turbo Tax needs to fix their product and train EXPERT support teams well to convey the message properly with customers.
For now I will be looking at alternate solutions suggested across than relying on Turbo tax import functionality to save my time and file taxes on time.
