Retirement tax questions

Thank you very much.   The important thing to me is when you said I need to keep track of my contributions.  I'll do that!

When I receive my tax docs, I know the broker will the $11,000 withdrawal, and it will be up to me to let the IRS know the cost basis was $10,000?   But documents won't spell out "only $1,000 is taxable" I assume?
