If you could be claimed as someone else's dependent for 2021 you were not eligible for a stimulus check. If you were eligible and did not receive the stimulus check, you could have used the recovery rebate credit on your 2021 tax return to get the 3rd EIP payment.
First check your online account with the IRS to see if the IRS shows an EIP payment for you. If it is not there, and you were not someone's dependent, then amend your 2021 return to use the recovery rebate credit in Federal Review.

Make sure you have saved a pdf of the original return before you amend. (If you do not save it as a pdf, the amended return will overwrite the original, and the original will be lost forever)

Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.
