Reply-To should normally not be set; its purpose is to route mail to
the proper address where you will receive it, in the event that your
outgoing mail server or other piece of software munges the From
address when you send mail, or similar.  This is pretty rare these
days but was once more common.  There are other uses but they're all
basically the same: you want replies to go to a different address than
the one in the From header.  In most cases your From address should be
the same as the address you receive mail at, and thus there's no
reason to set reply-to.

You can of course set it anyway, and usually it will have no effect;
but if you do so it's possible that you may interfere with other
software that has good reason to modify Reply-To on your behalf.
This, too, is rare these days.
