We are also subject to AMT and 1116 AMT was done properly for me. It is automatically picked up from "Comp Wks".
Please remember that line 18 calculations on form 1116 are DIFFERENT for "normal" 1116 and for AMT 1116. So if you see a different value in line 18 AMT 1116 form, that might be correct.
It is awful because the IRS gives instructions for calculating line 18 for the "normal" 1116 form in one document (instructions for 1116 Form), but instructions for calculating line 18 for 1116 AMT form are in another document (Instructions for AMT form).
