TDS is just tax deducted at source. This actually has nothing to do with the amount received. You definitely may have IT repercussions, but not TDS.
As per process the Bank may have to do due diligence while processing a high amount transaction. You wont get an OTP for an offline transaction. But ideally a call should have been made.
Please report this as fraud to the branch if the transaction hasnt been initiated by you. Please ask them to verify the signatures. Banks do take help of signature experts in case of frauds .
