I recently moved into a house where the previous owner put in a shed and ran two 10/2 w/Ground UF cables to it, and connected both cables to a 20A twin breaker with handle ties. The other end in the shed is barely finished but one cable is going to a few outlets and one to a few lights. A few questions:

Is this even to code/safe? Not sure if it violates the "only one circuit to an outbuilding rule". There doesn't appear to be any ground rod installed, but I understand with a 20A breaker I don't necessarily need one?

Could I put both cables into a sub panel to get 110/220 if I need it in the future? If so, how should I handle the neutrals? Hook both up to the neutral bus bar or only use one? My gut is only one should be used

It not code to run two circuits to detached structure.
You can't combine two cable and use it as a feeder. Code requires all wires to be in the same enclosure, one conduit or one three wire cable.

That's what I was afraid of, thanks for the confirmation. I guess what i'll do to be safe is to disconnect one of the 10/2 lines on both ends and switch to a single breaker. 220 would have been nice but not a hard requirement, better safe than sorry

Just run a 10/3 Wg to the shed, change the breaker to 30 amp 2 pole, and add a 4 circuit panel in the shed.
