I also changed the calculation method from the simplified AMT calculation for foreign tax credit to the so called complicated method. Then I e-filed my return and it is accepted by IRS on the same day.
I am really quite happy about it!
Now just for sure, I did some research on the so called the FTC AMT calculation method, and I found a pdf file at IRS website:
https://www.irs.gov/pub/irs-utl/int_p_062.pdf
It mentioned the FTC AMT calculation method.
It seems to me that there are really no differences between the simplified vs complicated method for the calculation if the foreign tax credit is not huge and if you do not have so called carry-forward or carry-back foreign tax credit situation.
Anyway, I learnt a lot from this message board, and I thank you all for contributing solution ideas to this topic.
Good luck to you all.
