I'm trying my best since this is for a college application essay:
What is the difference between "on-track" and "on track" and which one should I use?
Here is the sentence I'm using:
Taking responsibility for my actions and keeping myself on-track was one of the most important lessons I learned last year.
Grammarly keeps telling me I'm wrong and I want to know why.

Grammarly, which normally should be taken as a guide to correct usage not a definitive oracle, is, in this case, correct. If you try to Google "on-track" the only hits you get will be for the un-hyphenated "on track".
This means that major dictionaries such as Collins don't recognise "on-track" as an accepted hyphenated word.
You do see it sometimes but it's better practice to use it as a phrase rather than as a hyphenated word.
