If you indicated on your return that you "can be claimed as a dependent" then you are not eligible for a stimulus payment. You have two options.
1. Since you were not claimed you can amend your return to indicate that you "Cannot" be claimed as a dependent and once processed and you meet the the income qualifications (less than $75,000) you will be eligible for a payment this year.
2. When you file your 2020 return be sure to indicate that you cannot be claimed as a dependent and since you did not receive your stimulus payment this year you will get it with your 2020 refund.
