I can't see how to put my banking info into my account, when I follow the video I see what's to be done, yet when I get to my account I get nothing there. Its a blank screen, Kindle has been e-mailing me asking me to add my bank info, I'll do when they let me. can someone help me? is there a number I could call.
I use Google Chrome. It's an excellent browser, even if part of the Alphabet empire. (To balance it, my default web browser is Microsoft's Bing.)
There is also the possibility that you are logging in with the wrong email address. Is your log-in the same address that KDP is sending to?
Just to head off another often-confusing issue, Amazon wants to see your home-country tax ID number, i.e. Social Security number for US residents, National Insurance number for UK residents, etc. That's important, and it represents a change over the situation a few years ago.
(Don't trust KDP to publish a print edition. Don't trust CreateSpace to publish an ebook. Each does one thing well and the other thing poorly.)
