If i pay rent but my landlord takes cash and wont sign a legal lease agreement how should i file my taxes?

We have a basic hand written paper that say my name will pay $XXX a month for rent and that’s basically our rent agreement. We don’t really have any legal documentation stating he is receiving the money from me. I just have transactions of my withdrawals of rent money when it is due to be given to him. Will this make things different when i file? I know it asks for a renters paper while filing but I don’t have one and he wont provide me with one to use.
