Identifying C wire

Trying to figure out if I already have an attached C wire. I hope the picture is attached. Iím thinking the upper right screw is the C wire attachment? Also, looks like the lower left whitedetached from the lower left screw heater connection? Thanks in advance. Dave

Welcome to the forums.

Added a labeled picture. I had to flip it to get the labeling correct.

The white wire on the C terminal goes to the outside condenser along with its red counterpart that is connected to the yellow thermostat wire. (orange wire nut)

If you are asking if you have a C connection to your thermostat..... I'd say no.
I can see a white, green, red and yellow to the stat.

Look closely at the thermostat cable.... sometimes there is a spare wire cut off.
