What is my "activity level"?

Trying to determine my TDEE so any help would be great! C:

On Monday, Wednesday and Friday, I do 15 - 20 minutes of some lower body pilates, followed by 30 - 35 minutes of weight lifting, followed by 30 - 45 minutes of walking at 3.0 - 3.5 mph.

On Tuesday and Thursday, I just walk for about 75 minutes.

At least, this is what I track. Outside of what I count as I exercise, I usually clean for an hour or so a day, or play WII, or, as of late, walk around in my large backyard for about....2 hours. After my exercise.

So am I lightly active or moderately active? Should I cut out that other walking that I do?
