I am amending my 2018 taxes - incorrect cost basis on 1099-B. Do I need to include proof with the return (cost is shown on my work Earning Statement).

No, you do not need to include proof. When the IRS reviews your amended return, they will ask for verification of amounts if they want you to prove the amendment.
