How can I amend a 1065 return?

[Alva124]

I am trying to amend a 1065 return under the BBA. According to Rev. Proc. 2021-29 the Partnership which I am trying to amend does not qualify to do so by marking the "Amended" Box on the return and K-1's. 

I started doing the 1065-X but stumbled upon this intuit help article stating "Form 1065-X can't be used to amend a previously e-filed return".  (Amending a partnership return in Lacerte - Intuit Accountants Community). I e-filed the return so, does that mean I cant file a 1065-X now? How should I amend the 1065 return?

You need to do an Administrative Adjustment Request AAR. Look that up. I think it will be part of the 2021 return.
