In early March 2020 I filed a final 1040 for a client who died during 2019.  She was widowed and had no surviving spouse or children who would qualify for the stimulus.  This week her estate administrator received a $1200 stimulus payment and would like to return it to IRS.  I am shocked that they made the payment considering the final 1040 had already been filed for 2019.  Does anyone have a clue how to go about doing this?  Any suggestions will be greatly appreciated.   Thanks very much!
