Secure 2.0 domestic violence withdrawal

I plan to withdraw $10k from my IRA Share account from my Credit Union to pay for my legal fees and costs in a domestic violence restraining order against an ex under the new SECURE 2.0 Act’s domestic violence provision: “Section 314 of the SECURE 2.0 Act beginning in 2024 allows a participant who is a survivor of domestic violence to receive a penalty free distribution from their retirement account (401(k), 403(b), and 457(b) plans).”

How can I be sure I don’t pay the penalty? My 401k administrator says my employer doesn’t have the option available but rather a hardship loan withdrawal. So I am going to my credit union which has my IRA to take a withdrawal but it doesn’t seem like anyone is familiar with Secure 2.0. 

is this withdrawal that just gets reported on next year’s taxes? Does anyone know how such a withdrawal happens?
