After you file

If you did not receive the 2019 or 2020 stimulus payments, then your two payments would total $1800.  If you are entitled to a refund from other income taxes that you had paid in 2020, then that refund would have been added to the $1800 for stimulus payments.  

You will need to review your return to see if all of your income and payments have been recorded for wages, interest, pensions, self-employment or other sources of income.
