Dear@MarilynG1 ,
Below are quotes from the TurboTax Data Source for Form 1116 Lines 1a and 3d. Both lines include values from Form 2555. Note that the TurboTax FTC Computation Worksheet breaks down Form 1116 Line 1a into 13 subparts (a through m).
Here is the TurboTax Data Source for Form 1116 Line 1 (subpart e: "From Form 2555 Foreign earned income"): "If General category is indicated AND if the Income Excluded on Form 2555 Smart Worksheet has an entry in the column, then from the indicated Form 2555, line 27, LESS the indicated Form 2555, line 45, PLUS any amount entered on the indicated Form 2555 to the left of line 45, to the indicated column."
Thus, TurboTax Form 1116 Line 1 subpart e = Form 2555 Line 27- Form 2555 Line 45 + Form 2555 Line 45 write-in (if any).
Here is the TurboTax Data Source for Form 1116 Line 3d: "From the corresponding copy of the Foreign Tax Credit Computation Worksheet, line 1f of the corresponding column. Additionally, if this is a General category of income (Box d is marked above), and there is an entry in the related column in the Income Excluded on Form 2555 Smart Worksheet on the Foreign Tax Credit Computation Worksheet, then from the corresponding copy of the Foreign Tax Credit Computation Worksheet, line 1f of the corresponding column, PLUS Form 2555, line 45, of the indicated copy(ies) of Form 2555."
Thus, TurboTax Form 1116 Line 3d = Form 1116 Line 1 + Form 2555 Line 45.
