What should I do with 20k?

I’m 24F, work as a nurse and live at home.

I have 10K in a roboinvestor and 10k in an emergency savings account. I also have no debt.

I don’t have plans to move out anytime soon (will prob leave once I’m married) and just feel like my money is sitting in my emergency savings not doing anything. I make 4% interest on it.

My only expenses are gym membership, groceries, gas (I drive a lot for work), and car insurance (my car is paid off)

I spend about $600-$800 monthly (half of that is my car insurance)

I don’t know much about money so any tips would help. My financial goals are more money tbh, but I’m not really saving for anything right now.
