A parent claims themself in 2020 simply to get both EIP1 & EIP2 as a $1800 refund and also received EIP3 as a direct deposit later in 2021. If the parent's daughter goes back to claiming her again for 2021 can the daughter legally claim EIP3 for her mom on the recovery rebate credit form? ProSeries does show a $1400 credit for the parent. Is there any information available that specifically states that double dipping will not be allowed for 2021 taxes?

Thanks for your help
