Is there any advantages for Roth IRA to start now?

I will graduate this summer. I am a designer not a market or fiancial specialist so i tried my best to read these channels' reddit posts.. My left money has been in a 529 college account. The account does not have a time limit so I am not required to withdrawl or transfer money.
The value, $9k, can roll over to Roth IRA, or i can pull the money out to be taxed and get 10% taxed more.

Also, a relative passing has left me about $50k. It has lost $300 since the passing 8 months ago. Should I be buying stock, and investing with it now at these odd times? Or, should I leave it in the account? Should I put some into the 529 and roll over that portion with $9k?

Are there any advantages to invest into an IRA starting this year???
