TPG has taken most of my tax return.

I did my taxes, and they were adjusted due to me putting in the wrong amount which I understand and I CALLED AND CONFIRMED with them how much I was going to get back from them after the adjustment. We have no offsets and we do not pay child support so there was no reason for money to be missing. The money sent to TPG was over 6000$ but TPG decided to take most of it and send me only 2,000$ that is not okay and I'm beyond upset this is ridiculous and I want the money I was supposed to recieve because again I confirmed with the IRS the amount I was supposed to receive. I want my money turbo tax and tpg! I wi no longer be using turbotax in future years due to this experience. Basically stealing people's money. I want my money returned to me.
