i have some wood steps outside and have a lot of drywall mud left over from another job and thought i would use this to make a couple of patches

Nope. Drywall mud is not waterproof. Wood filler is. Use the right product for the job, and you will only have to do the job once.
I have found that patching exterior wood usually is a stopgap measure at best. Outside wood just has too much going against it for a patch to be really permanent. I will try hard to convince my customers to have the wood in question replaced, primed, and painted generously to make it last. And even then depending on the situation that part may still need to be worked on sometime on the future.. Look for reasons why this is happening and maybe address that situation. And of course it always comes down to how much money a person wants to devote to something.
Drywall mud will not last long at all. Try using automotive bondo. I have used it to fix windowsills that were rotted out. I just dug all the soft rotted places out, mixed up the bondo, and sculpted it into the places it is needed.
If it’s just a little hole it works fine. Be sure to seal it before painting.
