You cannot "do" anything to speed up the processing of your amended return. It is taking the IRS about six months or even longer to process amended returns. If you do not get the 3rd stimulus in 2021 you will be able to reconcile it on your 2021 return next year, just like lots of people have had to do with the 1st and/or 2nd stimulus payments by using the recovery rebate credit on 2020 returns.
