I didn’t receive the stimulus payments. I am 19yr old college student. My parent didn’t get the stimulus for me. Am I eligible as I filed my taxes last year.

This IRS FAQ states:

Who's Eligible for the Second Round of Economic Impact Payments?

Generally, if you’re a U.S. citizen or U.S. resident alien, you may be eligible for $600 ($1,200  for a joint return), plus $600 for each qualifying child, if you (and your spouse if filing a joint return) aren’t a dependent of another taxpayer on a 2019 tax return, have a social security number (SSN) valid for employment and your adjusted gross income (AGI) does not exceed:

• $150,000 if married and filing a joint return or if filing as a qualifying widow or widower;
• $112,500 if filing as head of household; or
• $75,000 for eligible individuals using any other filing status

Your payment will be reduced by 5% of the amount by which your AGI exceeds the applicable threshold above.

If you have not received one or both of your stimulus checks, you will receive your payment in the form of a Recovery Rebate Credit on line 30 of your 2020 Federal tax return when you file.

TurboTax will compare your one or two stimulus payment amounts to the computations within TurboTax.  The computations within TurboTax are based upon the information that you have entered into the tax software.  If you are due an additional amount, it will be issued as a Recovery Rebate Credit (RRC) on line 30 of the 2020 1040 tax return.
