For very short-term things, i.e. today or tomorrow, a sticky note on my desktop that goes into recycling the moment it is done. For medium term things, a checklist manager like Google Keep. For longer term or complex things, then project management software like Jira. As another commenter suggested, treat these like a scrum.
For request that I or my team perform for others, it goes into a ticketing system 100%.
