Son Full Time Student with Campus Job and No Tax Taken Out

While working on my son's taxes through Turbotax I noticed tax not taken out of his checks. Our son is a college sophomore and had 2 jobs in 2024.  One job was on campus and that W-2 shows they did not take out Federal Tax.  Do I file this W-2 normal and they will take tax or is there some kind of exemption since he was part of work study?  His 2nd job was a co-op.  That W-2 did not take out city tax.  This is in a different city then his permanent home address.  Do I just file that W-2 in my city like normal and they will take tax?  He files his own tax return because he generally receives a return.
