Refund check trace for joint filing

 

  My spouse has filed tax returns with Single status for 2019 Tax returns in Jan 2020 and got her refund. I haven't filed my returns for 2019 at all. We had amended the tax returns in Nov 2020 knowing that we can file MFJ since our marriage was in 2019 and we have included her as primary tax payer since she filed already. We separated in Mar 2021 and filed for uncontested divorce. Now I have been notified in Jul 2021 that a refund check is coming soon but the refund check which is a significant amount never reached my mail. I have called IRS regd the status but they asked my spouse to call and my spouse won't talk to me. They were not able to see any amended return on my name but can see it on my spouse name. My online status does show refund is completed on Jul 30. Now most probable scenario is my spouse might have received the check since she is primary tax payer and not revealing it to me.  How do I find out refund check trace from IRS without my spouse involvement and confirm that she received it. I want to then hopefully claim my fair share of the refund.
