How do I get around this problem?

I’m trying to add some DVDs to my Amazon seller account and I’ve hit a problem that I’ve had before. They want me to “apply” to sell a brand by submitting the information on the image. I just want to sell some things I bought 20 years ago for extra cash. The last time that this happened a few years back I sent a message to the helpline and got zero help. Does anyone know how to get around this?
