Spending some months with a TDEE spreadsheet can be helpful but requires logging a lot of CI and weights -- if you go to any online TDEE calc you might overestimate your activity level.

I was surprised that running 6h/week and 15k/steps a day gave me an TDEE activity level at barely above "Light Exercise" and I need about 2460/day.

The "Moderate" activity level is if you actually work construction and haul bricks all day!
