I know there are a lot of people on YT who can give you excellent advise on this. You may want to try a search on this topic.
I have seen Petsmart offers potty training classes so maybe you could check into that. I sure wouldn't feel bad leaving them penned in the kitchen if I were you, I left mine in crates when I was working, but came home at lunch to let them out. It took about a year for Daisy to catch on.
I still praise them big time when they go potty and poop outside and they know they are good doggies, they are so proud of themselves. Now I don't have any more accidents unless someone is sick in the night. Treats helped me a lot with potty training.
Good luck, believe me I know how frustrating this is.
