Annuity - how to input cost basis on turbotax

[lou_renshaw]

I have the premier turbotax download.  

I received a 1099-R from Prudential.  They have the gross compensation and the taxable amount the same.  They did NOT check the taxable amount not determined.  I looked at Prudential website, and they say that they report the full earnings on 1099-R, and do not keep track of cost basis for non-qualified accounts.  They say we are supposed to adjust it on our tax return.

Wouldn't that get the IRS attention?  How can I adjust it on turbotax?  I do not see a question and answer section that asks about cost basis?  

I should not be paying taxes on most of my annuity income, so how do I fix this?

Thank you!
