Accidentally deposited significantly more than I have in my bank, funds, or investment account in Robinhood

Either it was a glitch or I typoed. I apparently initiated a deposit of 15k on the 30th. From a bank account I planned to close tomorrow. I haven’t touched any of the instant deposit or margin. I have 3k in my actual invest account and like 40 dollars in the bank account. I noticed too late to cancel the transfer. Naturally, it was a holiday yesterday and today so I can’t reach anybody at either institution.

How fucked am I? I already have been close to the wire on funds so planned to stop investing and withdraw all cash tomorrow on top of closing that other account, until I saw this. Does Robinhood charge for bounced transactions? Why would my bank even clear this?

If there’s a fee from Robinhood ontop of my overdraft fee I’m almost tempted to just gamble on spx, spy, QQQ options or some other decent odd lotto ticket and if it fails just $ROPE in my basement because I’m quite literally fucked if there’s a significant fee.
