Hi Anthony, here's a kind of quick demo on how you can make a better shaped surface for things like that one curved piece.

When you have outline curves that are not very regular, like one portion is way longer than the other side or stuff like that, it doesn't work so great to try and build a surface directly to those curves. I mean you can do it, but the surface will tend be chaotic in the irregular areas, often times there will be things like small folds back over itself and things like that. You may be able to get away with that for some things, but not if you want to fillet them.

So instead of trying to compress in a single surface directly to the boundary, usually a better way is to build a larger and more simply shaped surface and then trim it.

So in your case that would look something like this:








Techniques like this (build larger than trim) tend to be a way to build a higher quality more evenly shaped model rather than going around and trying to fill in things "patch by patch". You can use the "patch by patch" method where things have a nice even topology but not when pieces are changing rapidly or compressing together or stuff like that.
