Foreign Soucre Income on k-3 coded as US

I have foreign source income (qualified dividends) reported to me on schedule k-3, Part II section 1, line 8.  The country code associated with this income is US, which is the United States.  I am an American so I do not know why US income is being reported to me as foreign source income on schedule k-3.  Do I report this "US" coded income as foreign source income when completing form 1116?  Or do I assume the income is sourced from the US and not report it on Form 1116?
