The prediction distribution is that of $$X_t \vert Y_1=y^*_1,\dots,Y_{t-1}=y^*_{t-1},$$ where \(X_t\), \(Y_t\) are the latent state and observable processes, respectively, and \(y^*_t\) is the data, at time \(t\).
The prediction variance is therefore the variance of this distribution $$\mathrm{Var}[X_t \vert Y_1=y^*_1,\dots,Y_{t-1}=y^*_{t-1}].$$
