I don't know. I just submitted ours this morning and it says they are not processing them till the 30th. I would double check that its the exact amount you expected to receive.
Not true. If an deposit is made into your account by mistake, doesnt matter if it was your account, its not your money, and it can be taken out, and if that draws your account neg you will be held accountable.
Used to work at a bank and saw that happen many times.
