I'm not sure. I know that dNTPs have three parts which are the nitrogenous base, a deoxyribose sugar, and a phosphate group. From the three components that is know I want to say that DNA polymerase can catalyze the DNA strand from elongation by removing the phosphate group from the dNTPs because the phosphate from a nucleotide will bond with 3' end of another nucleotide thus forming a phosphodiester bond. This formation is by dehydration synthesis.

I just want to see if I have the right points down, or if I am completely wrong in my explanation and reasoning. If I am I would greatly appreciate it if someone would steer me in the right direction.

Yes, it removes 2 phosphates, leaving 1 phosphate that creates the phosphodiester bond between the two sugar molecules.  The loss of two Pi releases energy needed to catalyze the elongation.

Pretty picture of it:
