Owed feds money, they deposited money in my account as if refund. Who to talk to

Hi folks,  

E-filed 2024 taxes, owe feds $x.  Sent personal check in the amount of $x three days ago to IRS service center.

Yesterday, the feds deposited $x in my checking account, as if I was supposed receive a refund.

Logged into IRS site.  Don't see any info on this topic or way to communicate with IRS.  They don't show my refund status.  Called 1040 number.  All automated.  Did not see any way to communicate with someone.

Any thought on how to contact IRS to let them know they incorrectly gave me a refund?

Thanks,
Kevinco
