My parents are looking for specifics on how i answered for my housing since im technically renting their home

There aren't questions about your housing on your federal tax return.  Are you looking for information about a particular state return such as a state tax credit for renter's claimed? 

Your federal return would not have asked anything at all about your rent.  Rent is not deductible on a federal return.  If you entered anything at all about rent it could only have been on your state return.

RENT

There is not a rent deduction or credit on your Federal return.  If your state has anything for renters you will be prompted to enter your rent info when you complete your state return.  As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, Rhode Island, Vermont, Washington DC, and Wisconsin.
