Form 1116 Computation Worksheet Issue

Hi,

Turbotax is erroring out because it needs the numbers for Lines 4b(1)b and 4b(1)c as shown in the highlighted cells of Form 1116 Computation Worksheet. The EasyStep interview process does not create these two numbers, so they have to be entered in Forms mode. I had no investment interest expenses, but I can't get rid of the zeros on Line 4b(1)a, so I must supply the following two numbers TurboTax is asking for:

Line 4b(1)b: Adjusted basis of investment assets generating foreign income

Line 4b(1)c: Adjusted basis of total investment assets

Please help me calculate these numbers.

Thanks!
