怎么把给nephew 存的529账户里的钱转到他父母给他开的529 账户 tax free?

昨天打电话问Fidelity 说可以， 填529 rollover 就行。 今天收到fidelity message 说”Since the rollover is going from one participant to another, this is going to be considered a non-qualified distribution with potential tax consequences. In order to process this request properly, the participant of the account where the funds are leaving must submit a letter of instruction detailing the transaction and that they are aware that they are taking a non-qualified distribution.

Any requests over $10,000 requires a Medallion signature guarantee. ”

前后矛盾

有没有哪位高手指导一下？谢谢
