The correct connection is to connect one leg of 1K resistor between 20K resistor and capacitor, and the other leg is grounded.

In fact, it can be directly coupled, because the capacitance of 0. 1 microfarad is equivalent to a short circuit with respect to the frequency of1m. The capacitor can be directly connected to the noninverting terminal, and then the noninverting terminal can be grounded with a 20K resistor.
