Hi Taxdragon29

My apology for this late reply,

I am sorry to hear that you were not able to claim the Recovery Rebate Credit on the 2020 tax return.

It is unusual that the additional amount was not given to you at filing. It is possible that there is something answered incorrectly in your 2020 tax return that needs to be corrected. If that is the case, you would certainly want to amend your 2020 tax return to correct the mistake so that you may receive the additional credit. Please consider giving us a call so that we may address this issue with you in hopes of correcting the problem.

This issue cannot be corrected, as of yet, by filing in 2021.
