Who was the "someone" that filed your tax return? For what tax year? Did they use TurboTax? Are they not willing to give you a copy of your tax return? Did they tell you the amount of your refund? How long ago was the return filed?
Check the IRS site for a transcript of your return. And check the your IRS online account to see what it shows for you.
You can get a free transcript from the IRS or for a fee of $30, an actual copy of your tax return.
