upper bound for $L(1,chi^2)$

Suppose $chi$ is a complex number. We know $chi bar{chi}=chi^2.$



Can anyone give me a reference for an upper bound for $L(1,chi^2)?$



I know there exists upper bounds for $L(1,chi),$ but I could not find any for $L(1,chi^2)$.

    For $chi$ primitive, $chi^m$ can be non-primitive or even the principal character, that's the only difference. If the order of $chi$ is coprime with $m$ then $chi^m$ is primitive.
