Timothy Step 0: your rear wheel is true Step 1: with the bike on the ground, open the QR so you are sure the frame is fully dropped down on the vertical dropouts. Close the QR Step 2: measure clearances at all four points: both sides at the chainstays and both sides at the seatstays, write those down Step 3: remove the rear wheel and put it back in backwards, making super sure that the wheel is fully in the dropouts again. close the QR Step 4: make the same four measurements
If you don't have a good way to do measurements, fine, eyeball it. IF your wheel is exactly centered relative to the seatstays both times, then the wheel is dished correctly. IF the wheel is centered exactly relative to the seatstays both times and is offcenter towards the right chainstay both times, then your rear end has an imperfection of some kind. IF your wheel position changed both at the chainstays and at the seatstays when you flipped it around, then your wheel is not perfectly dished. Consider taking care of that and repeating. The amount it moved is double the amount your wheel is out of dish. For example, if your wheel is 2mm out of dish, it'll "move" 4mm when you flip it. IF your wheel changed in position at the chainstays but not at the seatstays, or vice versa then you are not being careful enough when you are getting the wheel seated in the dropouts. Repeat until you are getting consistent results. Let me know if you need help walking through this.
