The score is the least important part of your credit file. You and your father should each pull all 3 of your credit reports (Transunion, Experian, Equifax) for free from www.annualcreditreport.com. Make sure each item belongs to the correct person. (You say you have never borrowed money but have some inquiries, presumably your father has a few loans and so forth.)
As long as the items in your file belong to you, then the scores being the same is probably a coincidence.
Now, if you look at the Turbo® app or web site and you see only your father's loan accounts, then you have somehow accidentally tapped his credit file, but that seems very unlikely to happen by accident. You would need to log out of your account and create a new account that was linked to your credit file in that case. But if you are seeing the correct information (addresses, loans, inquiries listed only belong to you) then the score is probably a coincidence.
