best way to maximize my savings?

i have about $22,000 in my regular savings account at my credit union. i know that there are better ways to manage/invest the money as opposed to just letting it sit in this account but i’m not sure where to start. so, i’m looking for any advice/tips on what to do (roth IRA or other retirement account, investments, etc). some extra context - i’m currently working a part time minimum wage job a which mostly just covers my living expenses and i don’t have any debt or loans.

any thoughts would be so appreciated!!
