Income call
For income on VOO you already hold: sell the Sep 25 $718 call and take $138 now. If VOO climbs to $718 by Sep 25, your 100 shares are sold at $718, so only do it if you're happy selling there.
If it climbs past $718 your 100 shares are sold at $718 and you keep the $138. That is the trade working, not a loss.
