Because neither of those are deductible on your federal tax return.
COMMUTING EXPENSES
The expenses of commuting to and from work (or to and from school) such as gas, tolls, bus fare, train fare, taxis, Uber rides, parking, etc. are not deductible on your Federal return. Sorry.
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, Rhode Island, Vermont, and Wisconsin.
