谢谢，ChatGPT也是像你这样说的。孩子已经有Roth IRA account. 我的理解只需再开个TIRA 就应该可

以做Backdoor　Roth　IRA了。以后不需要再开。

You can perform a Backdoor Roth IRA by transferring non-deductible contributions from a Traditional IRA to an existing Roth IRA. It doesn't have to be a new Roth IRA. The process involves making a non-deductible contribution to a Traditional IRA and then converting that amount to a Roth IRA.
