I am in the same boat. I think you need to fill out form 1120 (proforma) for the individual, which includes forms 1118, 8992, and 8993 and keep this for your tax calculation and FTC backup. These figures are then entered into 1040. I had also filed the 8992 at the individual level and for lack of guidance, I made an entry to other income to back out the GILTI income that flows from form 8992 with a reference to "GILTI taxed at Corp rates-See 982 tax on Sch. 2.
