you are a dependent if you meet certain conditions even if you are not claimed. the tests are.
Qualifying child
1) Related
2) Same principal abode as taxpayer for more than ½ the tax year. Temporary absences like for school are ignored
3) If not a full-time student, under 19 at the end of the tax year. If a full-time student under 24 at end of tax year.
Full -time means an individual who during each of 5 calendar months during the calendar year in which the taxable year of the taxpayer begins is a full-time student at an educational organization described in section 170(b)(1)(A)(ii), or is pursuing a full-time course of institutional on-farm training under the supervision of an accredited agent of an educational organization described in or of a State or political subdivision of a State.
4) Hasn’t provided over ½ his/her own support
of you provide over 1/2 your support, you can't be claimed as a qualifying child
the we have to see if you meet the qualifying relative tests
Qualifying Relative
- meets relationship test - this test is met
- your gross income for 2019 is less than $4,200
- you didn't provide over ½ your support
- isn’t a qualifying child of another taxpayer
if you are not a qualifying relative either then no one can claim you as a dependent
so you would not check the box that you can be claimed.
you teacher shouldn't be giving tax advice
but I doubt you'll get anything from the stimulus since it's based on 2018 returns.
