Most of your sketches have square or very small radius corners. Make them all the same or close to the same radius and see what the loft does. Or, make them square and loft it. You'll get a square corner obviously. Then apply a fillet to that edge.

I noticed that Sketch1 is not constrained, or making any use of symmetry about the origin.

There are also redundent workplanes.
I would suggest reading these documents

You have a lot of bad profile sketches..... duplicate objects, Vertical
center lines should be construction type, No rails to guide the loft.

See attached image for ideas.....

I don't hoard the few clues I'm privy to and am going to give you
your very first re the subject: Section curves are derived from
complex surface mathematical models, not vise versa. What you are
doing is, basically, folly. Start with something simple and work
with it until you understand what you're doing and why, go from
there.

You're annoying.

Let me see...
Condescension: x5
Cryptic insults to parties unnamed: x3
Personal insult to OP: x2
Insinuation of superiority: x3
Off Topic: x0 (for a nice change...)

5+3+2+3 = 13 >5 :. DonkeyButt=Troll

(and yes I know, I have not helped the OP here.)

I don't know. I thought the advice was pretty "spot on" in this case.

Please feel free to ignore me.
I seriously doubt we share any common interests.

Sticks and stones may break my bones but
your 'personal attacks' will never hurt me.
