Installing smart thermostat
I purchased a ecobee smart thermostat with voice control it seems to requires a C wire or a power extender which came in the package. My old thermostat was battery-powered did not have a C terminal. Below is the wiring set up for my old thermostat:
I have a trane system model number below. I have read on here that with trane systems the B wire also services as the common wire.
This is the wiring set up on my trane’s control panel and the wiring bundles pictured below all 6 bundles have 3 together apart from the G wire.
What if anything do I need to do to get my ecobee smart thermostat wired, installed, and set up properly so that it works for both AC and heat?

Welcome to the forums.
Trane does use B as their C/common connection.
O ------------> orange ------------> O/B
B -------------> blue ---------------> C
G ------------> green -------------> G
R -------------> red ----------------> Rc
Y -------------> yellow ------------> Y1
W1/X2 ------> white --------------> W1/AUX
Set thermostat up for heat pump with back up electric heat.

It sounds like it's not running in heat pump mode.
Heat and cool are the same except for power on the O/B terminal to power the reversing valve into the cooling position. Confirm you have the O setting..... not B for....... the O/B programming.

How would I do that?
Would that need to be something I confirm that in the programming/set up of the device or would I need to take another look at the air handler’s control panel?

Go out to condenser..... with unit running.... check for 24vAC from O to B/C.
That is needed to set the reversing valve to cooling.
If that's ok.... remove the white wire from the thermostat and see if that stops the heat.

No problem with questions.
The wires are visible in your previous pictures..... the one of the splice.
The splice is 6 wires but only 5 go out to the condenser.
We're looking for a thermostat cable with red, blue, orange, yellow and white.
I don't see it clearly out at the condenser.
You want to measure between blue and orange.
