Common 24v C wire

Hello, I’m swapping out my old White-Rodgers series 80 thermostat for an Emerson Sensi Smart ‘stat. My old W-R ‘Stat did not have a common C wire; just red & white wires. There is an unused blue wire. Looking at my Honeywell RA832A, I see the red wire connected to the upper “T” terminal & the white wire connected to the lower “T” terminal. The blue wire was clipped off. Is there a terminal on my RA832A I can connect the unused blue wire as a common 24v C wire so I can wire up my Sensi Smart ‘stat?  I’d like to avoid using an additional 24v C Wire Adapter as a work around.
