All my foreign taxes have been on passive (dividend) income. I normally have > $600 of foreign tax a year, so elect to file a 1116. There was one year in the past where the income limitations resulted in not being able to claim all my foreign taxes, and I have been carrying this forward, claiming some each year as allowed.
My question is the form 1116 line 10 asks for a "detailed computation" of the carryover amount. In the past I've provided a non-descript statement but I'm wondering if I should just let "sleeping dogs lie" or try to provide more info on the carryover? If so, just what detailed compuation should I provide? I use tax prep software, and have to admit that I tend to press the "I believe" button when it comes to checking how the software comes up with 1116 / AMT-1116 data.
