If I am a full-time college student with no income (temporarily disabled/mobility issues) in 2023-- Is it okay to e-file my return with $0 net income as I couldn't work?

I was temporarily disabled and could not work in 2023. I am currently unemployed, but a full-time college student living with one of my parents. It says I am "ineligible" to e-file my return "but can do it by mail." I want to know if it is legal and perfectly okay to file a return with no income.
