A few questions...

Is this a new wallet?

If this is a new wallet with zero balance then you do not need to do anything except make sure that you have properly backed your wallet up. More details for of securing your wallet can be found here docs.qtum.org

If it is not a new wallet and you updated the wallet to v.0.19.1 after October 28th, then please read this article https://blog.qtum.org/you-missed-the-hard-fork-now-what-996bab6639de
