Not sure why you think a problem with entering your banking information required you to mail your tax return. You could have chosen to receive a check mailed to your address and you still could have e-filed the tax return. Something else was wrong---but we cannot see your tax return or your account.
Did you talk to customer support to sort out the issue? Or did you check with your own bank to see if there was some sort of mistake regarding the routing number or account number? Were you entering information for a U.S. bank? You cannot have direct deposit to a foreign bank.
