Did not report 1099

Hello,

I cashed out company stock options for $3,089 after taxes.  These options pay through a separate check from my employer.  I did not include the tax form from the stock provider in my return.  The IRS has sent me a bill for $671.  This is listed under securities. The IRS says I miss represent my income by the above amount.

 

My question is,  will amending my return by filling the return with the stock option tax doc erase or decrease this $671 bill?  I am not sure if I was given to much of a refund due to the reporting issue and the IRS is stating I owe it back or if the IRS dose not see that I have paid taxes on this income due to the reporting issue and once I report it properly the debt will be erased.     

 

In short, will filling the doc I missed make a difference?  

 

Thanks for the help.
