I used to have an old workout i created where i did 1000 push-ups a week and also weight trained and jogged/run. is that overtaxing my body?

Work out: Start at a slower pace and gradually build up. Your body will tell you if you are overdoing it. Might have a physical before you start.

Workout: At 20 y/o, if you're training for something like an ironman or crossfit competition or competition, this is not over taxing. But if you haven't done this in a while, you'll see early on that you won't have the same stamina before. I hope this was helpful, if this was helpful, please vote for me. Good luck and thanks!
