If this is in regards html attributes of a saved search (like a custom label that is aligned left, bolded, different color, etc), they took it out as of 2020.2. Netsuite Support said "This is because in the Custom Label (Saved Search Result) before the upgrade, you can run a Javascript code for the whole feature." @Dominic B is right. We filed a defect and it is a U4...and this was Dec 2020. The defect number is 611569 if that helps. I don't think it is going to be any time soon.
