Before you start a task, the time that you will have to wait before you receive your reward is written in the task description.
Usually, it takes 24 hours, but it can take up to 7 days for some tasks. More complicated tasks are verified manually.
If you still don't receive your reward after that time has passed, please contact JumpTask support and specify what is your BSC wallet address and for which provider's offer you have not received the bonus. Details on how to contact JumpTask support can be found here.
