If you did not receive those first two, then you will need to file your 2020 tax return to get the $$ credited to you.
You need to fill in absolutely everything else first so that all your 2020 Personal_Info/income/deductions/credits data has ben fully completed first, but then the software asks if you received either of the first two stimulus $$ during the Federal "Review" and you win need to indicate there that you received zero for both of them. That will then make sure the proper amounts are entered on line 30 (Corrected line #) of the form 1040 as "credits" for your 2020 taxes.
