Can this be used as a substitute for a general electric thqb2120gf? will it fit the same box as the ge breaker?

No, The code requires you to use the same breakers as your panel. GE you use GE or breakers that are certified for that panel.

Will the qf220a be a direct replacement for the qf220?

both are 20 amp breakers, both are 140/220v

Will this fit in a murry panel?

breakers and panel manufacturer have to match. do not mix and match

The manufacturer of my mini split specifies a “high harmonic” gfci breaker. is this a high harmonic breaker?

I'm not sure if it is but I've used this breaker on several hot tubs that required High harmonic GFCI Breakers and havnt had any issues. Just to make sure I would contact Siemens directly and ask.
