How about the everyday calories we burn without exercising, showering, watching t.v., house cleaning, shopping, sitting at the computer etc. how do we figure this out and are we suppose to log this into the exercise part.

Check out the activity level in your settings. Adjust it according to your level of activity. I'd call that sedentary from what you described. It automatically adjusts your recommended intake according to your statistics.

Thanks, so I will just log what actual exercises I do.

and do not consume the extra calories it gives back for exercising

Eating them back or not depends how you're using MFP. If you're using it as designed you are indeed supposed to eat back the exercise calories. They aren't factored into your daily calories until you log them in your exercise diary.
Test it yourself
my home > settings > update diet / fitness profile
set 0 minutes of planned exercise, save and view your daily calorie goal
now plan something crazy high like 3600 minutes of planned exercise. Save and view your identical calorie goal.
So if you've set MFP to "lose weight" at 0.5, 1 1.5 or 2 lbs per week your daily calories already include your deficit for weight loss at your chosen rate. eating back the exercise calories is "allowed" in that scenario. If you've got MFP set to maintain your weight but are using your exercise to create the deficit for weight loss you would then not want to eat them back.
Or if you're setting your profile up to suggestions from other sites such as the TDEE less deficit you don't eat the exercise calories back in that set up either because they're part of your TOTAL Daily Energy Expenditure.
