Thank you!
I don't need to amend 1040, no refund or extra tax is involved. but I will attach 1040x for sure.
I only need to revise 8582, I didn't put accumulated unallowed K1 loss correctly. I guess I can manually revise it. this needs to be revised from 2015 until 2021.
Should I revise them? the unallowed loss will affect the 2020 and 2021 tax refund.
