Settings and then
Unlock wallet for staking. You will be prompted to enter your wallet password, enter your password and click ‘OK’.

It may take several seconds for your wallet to actually begin staking, and the amount of time it will take for your wallet to find a successful stake will depend on how many coins you are staking and other factors.
Your coins will not be able to stake if they are ‘immature’. For more information on this and things related to staking see this article
