Do y'all have any suggestions on how to stimulate an unruly puppy?

I have a very smart 4 month old goldendoodle who loves getting into everything. She has no interest in her toys or chews. I’m at my wits end. She won’t respond to any correction or redirection. I puppy proofed tf out of my house but she still finds shit to get into. Idek where she gets some of the stuff she finds....
