I know what you're trying to say but pro tip you want to stop considering the eighth notes as "beats". They are "off-beats" and when you're counting out-loud or in your head it's better to count it as 1-and-2-and-3-and instead of 1-2-3-4-5-6. It may not seem important but this piece is like a waltz because it's meant to be felt in 3. but I'm willing to bet the way you count in your head and out loud WILL affect the sound and make it more rhythmically pleasing. (You may already be aware of this but wanted to say it just in case). When I was starting out I did the same thing though, something I learned after a while.

Using your terminology yes it's supposed to start on beat 2 (perhaps a more correct way is on the "and" of 1). The whole run in the left hand with those small little notes (as I see it on my score) lasts a quarter note. So that means you should be playing 5 notes in your left hand per eighth note.

This means the run starts slightly before the (A+C#) come in in the right hand.

Best way to practice is slowly. Make sure you got the left hand down 100% alone with metronome or counting out loud. If you're trying to put this together hands together before you can play that run fast hands alone it's probably not ideal.
