Daughter was FT student in 2023 and has a W-2 from Dept of Interior. She lives in CO but W-2 shows tax withheld for KS. Does she need to file both CO and KS returns?

She's getting a 100% refund of the federal taxes withheld and it seems like she should be getting back her state tax withholding too. But in TurboTax (free) it's not showing any refund for CO. I haven't added KS as another return to be filed since I don't know if that's what we're supposed to do. Perhaps if we also filed a KS return for her, it would show a refund from that one?

She won’t get a refund from CO if nothing was withheld by that state. Filing a non resident return for KS will get her tax withheld back. You could try filing for free at the KS site.

There's information specifically missing from your post, but inferred:

Your daughter is a CO resident.

She worked in KS.

She does not have enough income to be required to file a tax return

But she will get a refund of withholding if she does file. 

She should file a KS non resident tax return to get a refund. 

This is the general rule: The income is work state (WS) source income since it was earned there. Resident States (RS) tax all their resident's income, regardless of where earned. You will file a non-resident tax return for the WS and report the WS income. You will file a full year resident return for the RS, reporting all your income. The RS will give you a credit, or partial credit for any tax paid to the WS.
