yes. Physically talking the additional weight will make it harder because you are lifting additional weight. But this also means that you will be expending more calories than someone without the additional 20 lbs. so they will help you lose the 20 faster.
If you just recently gained the 20, you probably will not be able to so as many sit ups as before. If you are new to sit ups then your muscles may be weak also and that will make it harder to do them. But either way the more you practice the easier it will get. So to still get improvement you will need to increase the number of sit ups occasionally.
A good rule of thumb for when to increase is when you don't feel the aftereffects the next day you need to increase how many sit ups you do.

Yes, to some degree: two people with the same muscle strength and aerobic conditioning, but one heavier than the other, won't be able to do the same amount of exercise using resistance from gravity's effect on the body, since one is doing more work hauling the extra weight around. I don't know how much it would affect situps, since that uses resistance of only half the body weight and at an angle; and not sure just how much of an effect that 20 pounds would have (more weight would be more noticeable).

Its not so much about how many pounds overweight you are, its more about your heart health. If you work out regularly, your heart is healthier and you can endure more sit ups.
The more sit ups you do the stronger your abs and heart will get, and the easier it will be to do them.

Yes, if you are in shape you can do more. If you are fat and have no muscle it would be harder and maybe impossible. OOOh, but 20 pounds isn't that bad. You would only be able to do a lil less.

I don't really think so. Sit ups have a lot to do with endurance, so if you have strong stomach muscles you should be able to do an equivalent amount of sit ups as someone average weight.

you have to build up to how many you can do say within a minute or whatever. it shouldn't affect how many you do, just how fast you do it. your weight will probably slow you down, but don't give up. stick with it. it's so worth it. and it sometimes helps to buddy exercise. walking does wonders too trust me. i've seen the after affects of one who walked the weight off then started other exercises.

How fit you are often has little to do with how overweight you are and fitness determines how many pushups you can do.

Obviously.
More fat = less muscles.
Less muscles = less ability to do work.
less ability to do work = less sit ups.
By how much it will matter completely matters on your will to do the situps.
