After you file

@Anonymous_    thanks

1. well i completed the 1065 to be the best of my knowledge. there are no mistakes on it as best I can tell

2. I did in fact file it several months late. but then I also filed an extension for my personal return so im confident the IRS had the 1065 by the time they received the 1040

 

3. but that begs a more fundamental question... could the amt the irs is asking me for be solely due to the fact that i filed it late?
