How do I recover my Apple Account if I forgot the Username and Password?

You will either need to get the old account working again or you will have to hope you kept your receipt from Apple when you purchased the iPhone from them.

Apple has two related features, Activation Lock ( Activation Lock for iPhone and iPad - Apple Support ) and Find My ( iCloud+ - Find My - Apple ), which are designed to prevent anyone else from using an iPhone, iPad, or iPod touch if it's ever lost or stolen. Deactivation ( How to remove Activation Lock - Apple Support ) of either requires knowing the Apple ID and password that set the feature, or by placing a special request to Apple to reset the device. This Apple ID information essentially defines the current ownership of the device. If you do not know the required information, or do not have an Apple accepted proof of purchase, the device is otherwise useless to you.
