The client's tax return was rejected because it’s missing a 1095-A form. It turns out he's listed on his parents' 1095-A, but they already filed their taxes without claiming him as a dependent, since he wants to file as single and non-dependent. His father paid for 100% of the health insurance.

Is the client (son) responsible for the 1095-A? How should the 1095-A be allocated, and do the parents need to amend their return to reflect the correct allocation?
