1 day running with a GTX 1080 Ti @ 21 MH/s and I have 410/0/0 shares. I use Coinbase as my wallet, but when do I receive the payout?

1) Your hashrate is ridiculously low. On default settings, with "ETHlargement pill", you should get around 45MH/s on ethash. Search the forum for the ETH pill.
edit: i did it for you:
https://bitcointalk.org/index.php?topic=3370685.02) The pool will send you payment after getting the treshold 0.05ETH as a default minimum. Read the pool's FAQ / info.
