This is a high fee transaction yet still unconfirmed. I've checked mempool and there's a lot of unconfirmed transactions.
Try your luck pushing that transaction through:
https://www.viabtc.com/tools/txacceleratorOr use the bitaccelerate -
https://bitaccelerate.com/. Whenever I make btc transaction, I use this free accelerator afterwards. OP's transaction will be soon confirmed. But 19 hrs and still waiting, paying 176 sat/byte, usually that payment amount before will only take few minutes.
bitaccelerate only rebroadcast transaction but
https://www.viabtc.com/tools/txaccelerator is the only working accelerator. It seems to be beyond the limit due to requests.
I don't find bitaccelerate to be effective, I've used it a lot of times before when there's such congestion before but to no avail.
Btw, @OP, congratulations your transaction got 24 confirmations already. I think the thread is already good enough to be closed.
