My crypto invest is under $ 600.00. I did not receive any 1099 form regarding this. My question is whether I still need to report this for the tax return?

Yes, you must report if you had cryptocurrency or other digital assets you received (as a reward, award or payment for property or services); or sold, exchanged, or otherwise disposed of a digital asset (or a financial interest in a digital asset).  See Digital assets | Internal Revenue Service.
