Please see this Help Article for possible reasons as to why your refund was less than expected.
If you used Refund Transfer, in this public forum, we do not have access to any information regarding refund processing. It would be necessary to contact TPG for additional information. They are one who handles your refund if you elected to pay your fees with your refund. You can also check out this TPG Help Article to check on your refund.
