@johnson2133 ’s advice gets my vote.
I recognize I’m beating a dead horse, but in case anyone else reads this, the “active” thing is not an insult.
When I was a rifle in the Army, I was extraordinarily active. When I was in staff jobs, I was not. I still ran hard and did PT for 90-120 minutes every day, so I didn’t want to think I was sedentary; I kept eating the same way, and soon I was the fat staffer.
Most our jobs a these days require us to be sedentary to be working hard - so it isn’t saying someone is lazy, it’s just dialing in a relevant assumption for these calculators to get as accurate a starting point as possible.
All that said, @johnson2133 nailed it anyway; whatever you’re eating now is your starting point, so just track that and adjust from there.
