Hi, I received $99 out of $1,373 of my tax return from the IRS. I called their service line and they couldn’t help me. Can you tell me why they only sent me that much?

I already reached out to the IRS and their automated voicemail told me to wait till May 5 for any further questions regarding my return. But I would really like to know where the rest of the return went. I didn’t get notified that they would take it or that it was reduced at all. And if it happens to be an offset payment , I don’t believe I have anything to pay back. So I really have no idea. I’d like to know if I should expect the rest of it soon or if that was all I am going to get. Please help me. xxx.xxx.xxxx
