Ohio's Electoral College votes are cast for the winner of the state, not per district [1]. Of course you should vote for Biden (or whoever the ultimate candidate against Trump will be)!
[1] - "As a winner-takes-all state, the candidate that wins Ohio gets all 18 Electoral College votes.", https://www.ideastream.org/community/2020-10-21/how-are-ohios-electoral-college-votes-decided
So you are eager for Trump to win, then.
