Welcome to the forum.

Was that a typo of B9? Is that supposed to be b6b9?

I’ve never encountered that chord. If you have a MIDI keyboard, try Windows menu, MIDI Chord Detection. Play the notes and see what the program suggests.

I don’t play guitar so I have no clue, but I always imagined that if you shift all the fingers of an E chord up one fret, you get an F chord. So you must not be fretting all six strings?
