Am6
A minor triad with a major sixth added, which is why it is not simply a minor chord with a flat seventh.

What is true of it
Am6 is A, C, E and F♯ — 1, b3, 5 and 6 counted from A.
These are also the notes of F♯m7♭5/A and G♭m7♭5/A. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
On an instrument that cannot reach all 4, the 5 goes first, in that order.
The easiest of the 5 fingerings below is 504550: 4 fingers, held at the 4th fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
Where its notes are on the neck
The brass dots are A, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
