Just input all the client's info, client's income dropped in 2020;  if she claims her sister & HH, she would qualify for a partial Rebate Recovery Credit.  So can she really claim her sister & HH and the Rebate Recovery Credit for 2020, even though her sister received EIP 1 & 2 payments because sister filed a 2019 Tax Return?  Sister had Zero income in 2020 & 2019.
