If you don’t have an ownership interest on the deed, then it sounds like you are a rental agent acting for your parents. Your parents need to report the income and pay the taxes. If they then give you the rest of the proceeds, that’s fine but you should not be reporting the income or deducting expenses.
There may be a rare exception if you have a “constructive ownership” interest even though it is not on paper. But this is very tricky, and requires an analysis of the specific facts and circumstances of your case compared to different past Tax Court cases that have considered similar issues, and is far outside the ability of this forum to help you with.
I agree that you should see a local professional.
