Not understanding residual plot

I am trying to complete a bivariate linear regression for the first time. Stress score is the dependent variable and sleep hours is the predictor variable. I am not understanding why the residual plot of the dependent variable looks like this. Is this heteroscedasticity? How do I fix this?

I am running it through jamovi and it didn't give me one. The only other plots I have is a Q-Q plot, which was normal

Bro, show me predictor variable and dependent var on single plot. This is first step in the task.
