Recovery Rbate Credit 2021

I amending my 2021 tax return filing because the data entry for the Recovery Rebate Credit was not included or overlooked while filing through this service. I followed the prompts for amending through the website. I downloaded the tax appropriate tax file. I saved the record of the account. I even saved the overview of further instructions which confirms that the IRS owes the $1400. I am now following the steps to process the amendment on-line, using Desktop 2021; but I cannot find where I need to update the information for correcting the amount to enter for the Recovery Rebate Credit.

 

I am not superb with tax filing, but it seems that there have some missed steps in the total process of filing/amending. What am I supposed to do to obtain my refund expeditiously?
