TDEE and BMR

[Oopsididitagaintomorrow]

Hi, hoping someone can help as I'm getting so confused with this.
My TDEE is 2200 and BMR is 1834, been advised to eat between 1900 and 2000 for a loss, but not go below my BMR. At the moment I'm on 1950
Now I log everything in my Fitbit app, aiming for 1950 daily. Today I've eaten 1871 calories and it's telling me I'm over budget, which I understand as it's been my non-exercising day, and a bit of a slow day all around.

My question is, as long as I stick to my 1950 am I still in a defecit regardless of how many calories I've burned? (I try not to gauge too much on them as it's all done through my fitbit and probably not 100% accurate)
Thanking you lovely wise people x

You can tell MFP what you want your calorie allowance to be just go into your settings

I have done, I have set daily calories as 1950 x

I don't take any notice of the Kcals on MFP for exercise. Just stick to the kcal goal you have given yourself or it has given you and you will be fine.
