Girlfriend is 20 but Aadhaar says 17—what now?

You must first correct her Aadhaar card through UIDAI by submitting valid proof like birth certificate, 10th marksheet, or PAN card. Legally, she must be 18+ to marry. Marriage with a minor is void and punishable. Do not proceed with marriage until Aadhaar reflects the correct age. For further legal assistance contact us on our helpline number.
