Is it possible to create a curved surface from two splines and the closed sketch shown below?

There is a better way.

I recommend:

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

You should always strive to fully define your sketches.

A bit more work because you have splines, but as I start to add missing dimensions the geometry is currently at unexpected sizes.

I would use as few points as possible in a Spline.

I was able to closely replicate your Spline with only 3 points.

The best Spline might only have 2 points.

Blue curves should keep you awake at night.

I loft only the half.

Then mirror it.

Hi! Here is a solution close to your design intent (but not 100% correct) by using Revolve and Non-Uniform Scale. The resultant geometry is very smooth. You may convert it to Form for further tweaking.

Many thanks!

I just joined the forum and I'm new to Fusion but in my first post I'm amazed at all of the help I've received. Hopefully, someday I can help someone else.

There are a number of free tutorial courses Autodesk has created to help people learn the essentials.

My recommendation is that you start going through one or more of those, along with what you'll learn in this thread.

 

Lofting is an advanced topic I would not recommend for beginners.

 

@wersy has used a surface loft but has left out at least one curve. He had to because your sketch setup is incorrect in several aspects. 

It is not adequately constrained or dimensioned, for example.
