No. Qualification for the stimulus is based on your 2020 tax situation.
The IRS used the 2019 tax return of tax filers in the past, merely to get payments out as quickly as possible. But that does not change the fact that one's qualification for the stimulus payment is based on your 2020 tax status. For example, if you qualify to be claimed as a dependent on your 2020 tax return (which you will not file until 2021) then you do not qualify for the stimulus.
If you were an undergraduate college student in 2020 then chances are you DO NOT qualify for the stimulus payment and never will. It is most common for an undergraduate to qualify to be claimed as a dependent on their parent's tax return, and is extremely difficult for such a student to have sufficient ***EARNED*** income to support a claim they they provided more than half of their own support.
