Saving/Investing for a short time

Hi,

I got a sum of around $60K that I would like to put on the side for the next year or two, but at the same time maximize the interest I can get on it.

I’m debating if I should just put it in a HYSA or try to find a CD.

Any recommendations? Also, any suggestions when it comes to taxs on this saving approach?

Thank you!
