Are there any electricians out there?
I understand that I can use an unused stove circuit to feed a subpanel and most of the requirements to do it.
My most basic question is if the line is fed 220 by a doubled 30 AMP breaker will I have 2 X 30 AMP’s so I can feed a 20 and a 15 AMP circuit off of each half of the 220 or will I just have 30 AMP’s total in the subpanel?

"I understand that I can use an unused stove circuit to feed a subpanel and most of the requirements to do it."
First most "old stove circuits" are only wired with 3 wires. 2 Hots and a Neutral. They don't have a separate Equipment Grounding Conductor (ie, "the ground wire") and without that they can' be used to supply a sub-panel.
Also 30 amps would be unusual for a stove circuit. Min is 40 amps and some go upto 60.
Might have feed an oven or cooktop though.

I asume that you are talking about 120 v circuits.
Each Hot is limited to 30 amps. If you have all of the 120v load on one leg you can pull a max of 30 amps on that leg.
If you have 120 loads on each leg then you can draw a total of 30 amps on each leg.
So you can put a 20 amp circuit on one leg and 15 amp on the other leg.
In fact, depending on what the circuits are used for it might be possible to have both on one leg (or more practically additional circuits off the same 30 amp sub-panel).
