You are absolutely correct. The previous responses are just plain wrong. Jeepers.
If partnership did NOT elect out of CPAR on its adjustment year return - then it needs to file form 1065X-AMENDED RETURN OR ADMINISTRATIVE ADJUSTMENT REQUEST. Along with the form 1065X it must submit form 8985 and 8986 and provide Form 8986 to the partners (assuming it "pushes out" the adjustments". Based on the Form 8986 they receive, the partners then file form 8978 with their 1040 in order to pick up the adjustments in the year that they receive form 8986. As opposed to receiving an amended k-1 where they have to go back and amend their 1040 for the partnership's adjustment year. An 8082 is not required unless a partnership is electronically filing or claiming inconsistent treatment. Typically the partners don't have to go back and file amended returns for BBA Partnerships.
