How do I get to the accounts page?

I installed and launched the app and entered my yahoo account details, but there was a problem with credentials so it didnt work. I went to the Help to see how to delete this account and it says to go to the ‘accounts screen’. I can’t figure out how to get to the accounts. I’ve tried pressing and swiping everywhere but the only place I can see accounts in under Settings > Account Settings but there is no option to delete the account.
