I suspect they are asking for this in response to your answers to questions they asked when you uploaded. That is, does your video contain any images (not video, but pictures, etc.) that you added to it.
I agree with jackwolcott and rs170a. They don’t care about Vegas. They only care that you have the right to use the cartoons in your video.
Write a short blob about how you drew them and created them and no one else has the rights to them (assuming that’s true) and you should be fine. That’s what I do.
Their use of the word “software” is unfortunate and misleading. Sony does not have any rights to what you create, just like Adobe doesn’t have rights to what I create in Premiere Pro. Youtube just wants to make sure YOU have the rights to what you created.
