Follow up with your answer: Her  2/1/ 2021 contribution of $2,000 was for 2020 ROTH as she only contributed $5,000 in 2020.  Schwab said the earning from the $2,000 should goes to 2021 Tax Return.  So I am trying to get the correct number to put in the 2020 1099-R. 

Assuming the total earning from the $7,000 is $700.  That means the Total Return Distribution with gain made this year is $7,700.  I split the earning by  proportion.  That is earning for 2020 & 2021 are  $500 and $200 respectively.

Then on her   2020 1099-R  :  Is Box 1, Gross distribution $7,700 or $5,500 or $5,700 ?  As I believe Box 2  is $500 as $200 will be for 2021 Return.  What is the Code in Box 7, PJ too? Please advise.
