My parents did not get stimulus money for me lastyear and i was stillin high school turned 19 in dec 2020 and i did not get the stimulus either???

Parents do not receive stimulus checks for children older than 16.   If your parents claimed you as a dependent for 2020 then you are still not eligible for a stimulus check---dependents do not receive stimulus checks.

If you were in high school in 2020 that means you were a full-time student for 2020 and your parents can claim you as a dependent for 2020.

Here's who won't get a stimulus check:

• Children who are 17 or 18 years old.
• Many college students between the ages of 19 to 23.
• Adults who can be claimed as dependents.
• Nonresident aliens (in other words, those without a green card).
• Estates. 
• Individuals who earn more than $99,000 or married couples earning more than $198,000.
• People who haven't filed 2018 and 2019 tax returns.

Who's a "child"?

Older children are excluded because the bill relies on a tax-code definition of "child" that states a "qualifying child ... has not attained age 17." In other words, many high school juniors and seniors and their families won't receive a $500 check from the stimulus bill.
