Did you use the TurboTax Deluxe edition ($59) and a state tax return ($49)? If so, along with the service charge of $39 for the third party processor, SBTPG, that receives the federal tax refund, deducts the fees and service charge and deposits the remain refund in your account, the total charges would be $147 plus any applicable state sales taxes. This would be the reason for the $155 difference.
