the critical question is CAN you be claimed by your parents; not whether they WILL claim you in 2020. See the difference?
If they CAN claim you in 2020, you are ineligible for the stimulus.
if they CAN'T claim you in 2020, you are eligible for the $1200. In this case, just follow the questions in Turbo Tax and when you get to the end, there will be some questions to address toe stimulus. The credit will appear on Line 30 of Form 1040. It will increase your refund or decrease the tax you owe.
what is the $1500 you think you received from the CARES act - that doesn't resonate
