What do I need to do as a beneficiary in a will?

I have been informed by the executor of my grandmothers estate, that I am a beneficiary in her will. I've not seen the will, and have only had a phone call informing of this. My uncle is the executor and he offered me a low cash offer to basically get me out of the picture. I told him I could not accept that but I've not received any official notification of anything and I do not know if the will has been filed with the county. I've not seen the will myself. My grandmother passed away at the end of March, I was not informed until early July that I am a beneficiary. What are my next steps in protecting my interest?
