The irs applied my return to my ex husbands owed taxes. I’ve not been with him since 2/2019. Is there a way to get my refund back?

Why did you file a joint return ?    You should have filed an injured spouse form if you were filing jointly ... but you can file one by mail now. 

8379 is the Injured spouse form.  

To file an injured spouse go to
Federal Taxes or Personal (for H&B version)
Other Tax Situations
Other Tax Forms
Miscellaneous Tax Forms - click the Start or Update button
7th item, Report an injured or innocent spouse claim

Here is a blank form 8379

I filed single not jointly. I don’t live with him and have no access to his tax information or bank information.

Ok ... so if you had filed a joint return in the past and there was a balance due then the IRS will take the refunds from both of you until that debt is satisfied.   If he was to pay the debt and did not then this is a civil matter ... sue him.
