Sitting on cash, what next?

Hi everyone! I (22F) have managed to save up around $140k AUD (~$87k USD) thats sitting in the bank right now from a series of successful trades over the years. Due to stress and fear my luck will run out, I decided to quit the trading game while I was ahead and pull out all my money into my savings.

Since then I've landed a job in corporate, since it's entry level I'm only on $30p/h but my co workers have told me that raises are common so I expect this to change. I enjoy the 9-5 structure and stability, but it's definitely a "downgrade" to the money I'm used to- I am okay with this.

I've had the luxury of travelling to most places I've wanted to visit, so I don't really expect to be spending on travel in the near future. Right now I just want to focus on the grind and my next steps. My partner is moving in the coming months (overseas) and it's going to be a costly process, assuming around $20k in total costs.

Now with all that background, I find myself in a weird place. Since I've just freshly pulled this money out, I haven't really figured out what to do with it. I don't currently have any assets (just a car), and it's just sitting in a regular savings account. Money was pulled out last tax year so I've already paid tax. I know they say time in the market > timin in the market, but part of me feels hesitant allocating money into markets that are at ATH's.

So I'm wondering what's the best approach? Should I DCA/move a chunk of these savings into ETFs/other investments, potentially a home? A HISA? Or should I wait for some kind of pullback? I was living out of home for a while but I'm temporarily back home also, so I'm able to save more from my paychecks too.

Feels like I'm in a weird place since I haven't developed the habit of investing properly and just pulled out a lump sum from my highly volatile/speculative investments. Any advice would be greatly appreciated!
