When there are multiple entries coming from separate Forms 1099-DIV in a return, all the entries are consolidated into one single column on Form 1116. In the Form 1116 instructions, pages 7-9 contain instructions that apply. When there are Qualified Dividends or Capital Gain Distributions within the return there is an additional calculation (special limitation) that needs to be done to determine the amount to include on line 1a of Form 1116. The instructions to do this calculation start in the section Foreign Qualified Dividends and Capital Gains (Losses) in the IRS Instructions for Form 1116.
This limitation calculation is done for you automatically by the TaxAct program if you enter the information on Forms 1099-DIV in the program and let that flow to Form 1116. If you manually complete Form 1116 you need to ensure the amounts are entered correctly for Lines 1a and 3d in Part I and Lines A, B and C in Part II. If there is not a need for the limitation calculation, you will normally find those lines to be calculated from:
Part I, Line 1a - Boxes 1a and 2a of Forms 1099-DIV
Part I, Line 3d - Boxes 1a and 2a of Forms 1099-DIV
Part II, Lines A, B and C - Box 6 of Forms 1099-DIV
Please note that Line 1a above will differ from Line 3d if the limitation calculation is required.
