Ok ok, we get that you put oil in it. You don't have to tell us over and over. Just because you put oil in it, means only that. Doesn't mean that it got to the right places, doesn't mean the top end didn't get oil starved, doesn't mean it didn't lock up because of oil starvation. You put oil in it, then it seized (maybe, still can't tell from what you're saying), that's all we know.
If your engine is seized, it will not turn. Meaning if it is in neutral, you cannot turn it with the kickstand. Meaning the kickstand doesn't move. If you can barely move it and it requires a lot of force, then it is still basically seized just not to the point of not moving at all.
