After you file

Unfortunately I have no outstanding debt that can be garnished or offset from my tax return yet I am missing over half of my tax return. I know part of it went to paying your fees (despite not wanting to do premium and not being allowed to use your free option)  but that was only $172. I was told I would be getting back over $1400 and got back a little over $600. I'm missing over $700 from my tax return that wasn't garnished. Apparently an accountant friend of mine said he has had multiple clients come in complaining of being shorted by turbotax. Should all of us contact the IRS and a lawyer to find out what is going on?
