Deductions & credits

That’s the thing…. Where does it state we entered into a contact with TPG, or that they are legally allowed to charge us fees? 
I signed an agreement with TurboTax/Intuit and my agreed upon fees were $219. 
my refund should have been over $5000, according to the IRS , yet TPG only deposited $2,200. 
where the hell is the rest of my refund?
