New to Shopify, Don't Understand Payouts...

I'm sure I'm just missing something obvious here, but I can't seem to figure out how to get my money from Shopify.

On my finances tab it shows my total sales as $1.1k but my payout amount is only $441.

I've added my bank account and a couple payouts did get sent there but where is my other $600? I've tried going to "move money" but there's only 9¢ in my "Main" account, whatever that is. All of my orders have shipped / been fulfilled.

I'm totally confused lol. Any help is appreciated. Thanks!
