Help...My refund is less and comes from "TPG PRODUCTS SBTPG LLC"

Like others....my refund is less by almost $300.  I don't ever get a lot back, so seeing that my refund was shorted, WITHOUT MY KNOWLEDGE, concerns me greatly.  How do I get this back?  Who authorized this?  I've been a life long user of TurboTax and I've suggested to others to use it as well.  Now I'm not so sure.  Help.
