Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
In the state of Texas, your claim for excess proceeds would be directed to the court system where the property is located
You will petition the court not more than two years after the sale of the property.
This is handled in TX Code 34.04 and you can read about the procedures, here: http://law.onecle.com/texas/tax/34.04.00.html
Please let me know if you need anything else. If not, please rate as "excellent" so that I may receive credit for assisting you today
