As I was moving old Schedule 40 conduit in my garage to get ready for a rewire, I found some had sheathed electrical cable running through them. Should I be concerned that sheathed electrical cable was used?

It is LEGAL to run sheathed electrical cable in conduit. Many people will say that it isn't, but nothing in the code prohibits it.

However, to pull sheathed electrical cable in conduit requires that the conduit be sized for a equivalent single wire with a diameter of the larged cross section of the cable.

Very likely the conduit is not large enough to PULL.

sheathed electrical cable can legally (by the NEC, by maybe not by local amendemnts) be run EXPOSED if it is tight against the surface of the wall.

Howver, where SUBJECT TO ABUSE it needs protection and can be sleaved with conduit. Since this is a short straight run it just has to be big enough to slip over the cable.

Subject to abuse is not defined, but most inspectors would say that on the surface of a garage qualifies.

In that conduit needs to metal or sch 80 PVC.

In my area sheathed electrical cable is not exceptable in conduit, and the reason the inspectors will give is that thier is not a proper way to connect a sheathed electrical cable cable coming out of a conduit into a junction box, a sheathed electrical cable cable requires a clamping connector approved for use on sheathed electrical cable, a conduit connector will let the sheathed electrical cable dangle loosley. however, if you are only protecting a short run where sheathed electrical cable is exposed to damage and not going into a junction box, it would probley pass if you put connectors with bushings on the end of the conduit to protect the jacket against the sharp edge of the end of the conduit....

Should I be concerned about sheathed electrical cable overheating while in conduit? It's 12/3 grounded, to a 20 amp fuse. Thanks!

Over heating is not a problem. The cable is designed to work in walls filled with insulation.

And the wire insulation is rated for 90C.
