FTC for Passive Income -

Hey all! Struggling with filing my US taxes via Turbo Tax.
 
I have passive income (1099-INT/DIV). All of this income is 100% taxed by Germany as I am a resident of Germany. I'm trying to fill out Form 1116 (FTC) for passive income to offset my US tax burden.
 
When I fill out the passive income Form 1116 in Turbo Tax, it shows a list of SOME of the 1099s to which I can attribute to Germany. But it does not list them all. It only lists the ones which had some foreign taxes withheld on the actual 1099 form. Those that did not have foreign taxes withheld at source are not listed.
 
Since I can only attribute a portion of my 1099s to Germany, this limits the amount I can claim as FTC (passive income) and increases my US tax burden, incorrectly. 
 
This seems like a bug. 
 
How can I signal to Turbo Tax that ALL my 1099 income is German-sourced and therefore should be included in the FTC calculation for passive income?
 
thanks,
tom
