Have a client that is allowed to take child every other year on tax return.  2020 is the year for him to take child as dependent.  The Recovery Rebate Credit is calculating a credit for the dependent of $1100.00 and adding it to their refund.  The mother took the child last year as a dependent and received the rebate for the child based on 2019 tax return.  Have researched this situation but can not find any clarification on how to handle this.  Any thoughts?  I am thinking not take the additional credit.
