Taxes on USO stock

I recently invested in USO (to be specific I bought in at $20.90 and got 95 shares). I invested without knowing the taxes that will be implemented on it, and now I am worried about how much in taxes I will have to pay.  I am aware I will receive a K-1 form at the end of the year, but from what I have read online I am scared about how much taxes I might have to pay. I've read online that some people ended up having to pay thousands in taxes even they did not make much in capital gains. Should I just sell my shares now?
