Form 1116 Explanation Statements

Upon completing form 1116, TurboTax is asking for an explanation statement for line 2 to explain "expenses definitely related to the income on line 1a"  and another explanation statement  for line 3 to explain "deductions not definitely related".  Since TurboTax automatically populates these lines after I enter my foreign income data from 1099's and k-1's, I have no idea what to enter for an explanation statement.  I don't know where TurboTax is getting these amounts from that show up on lines 2 and 3 of Form 1116.  TurboTax requires an explanation to complete the tax return.  What should I enter?
