Even if you didn't receive a 1099-K from Lyft, you still will enter the income earned from driving on a Schedule C.
To get started type Schedule C in the Find box of your open return. Then select the 'jump to' link. You will be able to take a limited amount of expenses that you may have had against your earnings in TurboTax Deluxe. If you just want to report the income only, then TurboTax Deluxe will be fine.
