I just got off the phone with the IRS and she said to mail the Injured Spouse form 8479 and write "Stimulus Payment 2020' at the top. To fill out the form, write the amount you supposed to get in the 'Payment' box and divide that amount between the injured spouse and the other spouse boxes. In my case it was $1450, then $725 and $725. Mail the form to: IRS, 5045 East Butler Ave., Fresno, CA, 93727 ATTN: Spousal Unit 2020.
Also, I noticed the Injured Spouse page on the IRS website has been updated to let us know we must file this form.
