After you file

Thanks again Critter-3.  I just saw that you already addressed my follow-on question!  Appreciate the help.  Sorry that I missed out on the capital losses for 3 years but at least I still have significant carryover to offset 2017 gains.  Not sure yet but I believe that I will still have some carryover for 2018-2019.  Just to confirm, missing the 3 year window forfeited my ability to file for amended refunds AND that capital gains that would have attributed to the forfeited refunds are lost?  

 

When I file 2014-2016 amended returns, is there a requirement to identify to the IRS that your amended return is outside of the allowable window?  They will look as if I am expecting a refund. 

 

Thanks again!
