HVAC experts of the OT

I didn’t expect you to have HVAC honestly.

Nest thermostat has little hub sensors that you can place throughout the house and your unit can run asked on those readings.

Thermostat must be near return air

I agree with Apex and notsince98 on the thermostat location. My thermostat is near the return air intake as well but I’m not having the same issue as you. I’d also recommend you look at Honeywell Smart Home thermostats T9 or T10 that allow you to place sensors in other rooms to communicate with the main thermostat and average temperatures out. Also look into Ecobee thermostats with the same functions. You didn’t say what type of thermostat you currently have - maybe malfunctioning to some degree?

Recommend you avoid NEST thermostats as they have the potential to cause serious issues. I’ll let you read what HVAC techs think of them LINK. There was a poster last week on this board last week that had an Nest thermostat causing a major malfunction of this HVAC.

You also may want check air balance between rooms - ducts usually have adjustable dampers installed inside the ducts near the supply plenum (up in the attic assuming your ducts are in the attic) that allow you adjust air flow to each room. Maybe they need to be adjusted. Ideally each room should be getting the same cfm of air flow on a square foot basis.

And do you keep your room doors open or closed? Ideally they should be open when not in use to allow a free flow of air from each room to the return plenum. That can contribute to the issue you are experiencing.

Lastly, a long shot, you can remove the current thermostat and look to see where the thermostat wires exist the wall if there is some insulation in the hole. If not put a little wad of insulation in there. Hot air from the attic can leak downward through the wall cavity to the thermostat, exiting the thermostat wire hole, and if not insulated, this keeps the thermostat warmer than it should allowing the HVAC to run longer and it doesn’t accurately reflect the true air temperature in the conditioned living area.

Obviously look at easy things first before you consider changing or moving the thermostat, but you might like some of the features these smart Honeywell or Ecobee thermostats have to offer.
