LinaJ2020, you have posted the link to "Form 1116 reject error" several times.
However, this link does not address the problem with AMT Form 1116 when using the Simplified Method.
Numerous people on this thread are discussing this issue, which is different from "1099-DIV amounts received from mutual funds" referred to in your link. Is this separate issue with AMT Form 1116 also under investigation?
One person said that if an e-filed return is rejected 5 times we must paper file. Is this true?
