What is the information for the bank that the direct deposit comes from? I have received a deposit, but the sender is unknown

Normally, a deposit direct from the IRS will be labeled "US Treasury" and if you used refund transfer to deduct your fees from your refund, the balance will be deposited by "Tax Products Group", "SBTPG", or Green Dot Bank.
