Foreign Tax credit handling - Frustrated

Friends,

 

I have two foreign source investment incomes (one from my mutual find and another from country where I lived). Entering these and taxes paid and figuring credit has taken more than 6 hours.  It is not straight forward at all. 

 

Now to my question : 

I have a form titled  Part III(1116) - Credit Carryback / Carryforward from my prior year returns. I cannot find anywhere to enter these. When I searched, I saw a post that mentioned I have to create a country "Carryback" but I am unable to add a country. Can some of you please reply with the info on how to enter "Credit Carryback  / Carryforward" from my prior year. 

 

Thank You
