Edit: Impedance value below has been found incorrect and would apply to a purely parallel circuit instead. Question has been answered in below comment. Deleting unrelevent information from this post to give the below answers more relevance.
Question : How do I find Voltage across R at 1000Hz. I built/measured VR in this circuit and VR should be about 2.2V at 1000Hz.
I have calculated:
XL = 20.734 Ohms
XC = 15915.494 Ohms
Z = 18.9908 Ohms < Z found to be incorrect. Now given correctly in comment below
