Yeah I don't see how a receptionist is an independent contractor.
Since your issue is only about the taxes you paid you should consult with a tax lawyer and/or CPA about filing the correct forms to ask the IRS to make a determination. You could also contact the Texas Workforce Commission and see if there is a way to make a complaint about the classification.
The IRS--as well as state tax/workforce authorities--are becoming increasingly interested in the (mis)classification of employees as evidenced by the Voluntary Classification Settlement Program (VCSP). The VCSP is an amnesty program of sorts and permits Employers to reclassify Independent Contractors as Employees with minimal penalty. I'm not sure if this is a program your employer would be interested in participating in. Alternatively, the IRS has set-up a Whistleblower program for misclassified employees. As the name suggests, this program requests misclassified workers to report the misclassification in exchange for amended tax treatment and in certain circumstances a reward. I suggest you seek the expertise of a local tax attorney for assistance in your matter.
