After you file

I need a copy of my 2019 tax return.  I was to get a refund and I finally got someone to talk to me at IRS. She stated I sent a schdule 3 with my return and it shows I was not due a refund. I efiled on 03/09/2020 it was accepted 03/11/2020 and estimated federal refund date was 04/01/2020.  She says  I need to see my return because it says I was not due a refund.  Please help!

Is there a number I can talk to someone about this?
