Question

Form 1099 B with box B and another with Box E marked.

Form 1099B has no date acquired or cost.  Only states date sold and proceeds. 

I can tell what is short and long term but what do I do about dates acquired and the cost basis?

Thank you

    Enter a date that makes the asset short or long.  You must provide a reasonable determination of cost basis or the IRS will consider it to be zero. Web sites with historical data or your broker may be able to help you.
