this is what my calc 1 professor gave us to brush up with when i took it a couple years back. they're just videos though, if you want everything to stick you'll have to spend some time grinding problems.

there are free textbooks here https://openstax.org/subjects/math
the instruction isn't very thorough, worth skimming when you need a quick refresh. use it for the exercises. I'd go through the Algebra + Trig book and Precalc, you'll need to understand trig pretty well to get through calc 2 hell
