Filed 2022 Taxes with Refund Freeze Since Feb 2024, Multiple Amended Returns I Didn't File, and $9,897 Balance Showing - What To Do?

I filed my 2022 taxes in March 2023 and still no refund. I'm getting seriously concerned about my situation. I checked my transcript today and it's showing a bunch of confusing entries that I don't understand. My transcript shows an account balance of -$10,897.00 as of Nov. 19, 2024, but I still haven't received anything. The information from my return shows I filed as Head of Household with 4 exemptions. My adjusted gross income was $19,949.00, taxable income $0.00, and tax per return $479.00. Looking at the transaction section, it shows: - Tax return filed on 03-26-2024 for $479.00 (code 150) - Refund freeze on 02-09-2024 (code 810) - Credit to my account on 04-16-2024 for -$3,881.00 (code 766) - Another credit on 04-16-2024 for -$10,413.00 (code 766) - Earned income credit on 04-16-2024 for -$8,258.00 (code 768) Then there are entries about amended returns: - "Amended tax return or claim forwarded for processing" on 05-02-2024 (code 971) - "Amended return filed" on 05-02-2024 (code 977) - Another "Amended tax return or claim forwarded for processing" on 09-10-2024 (code 971) - Another "Amended return filed" on 09-10-2024 (code 977) Then more recent activity: - Additional tax assessed on 11-12-2024 for $0.00 (code 290) - "Reduced or removed credit to your account" on 04-16-2024 for $514.00 (code 767) - Earned income credit on 04-16-2024 for -$172.00 (code 764) - "Reduced or removed credit to your account" on 04-16-2024 for $10,413.00 (code 767) - "Reduced or removed prior tax assessed" on 11-19-2024 for -$479.00 (code 291) - "Notice issued" on 11-19-2024 (code 971) I've checked Where's My Refund multiple times, but it just says "still processing." I've called the IRS repeatedly but can't get through to a human. I don't understand what all these codes mean or why there's a refund freeze. Why would they issue a notice on 11-19-2024? I haven't received anything in the mail. What should I do about this? Why is there a freeze on my refund? And what's with all these amended returns when I didn't file any amendments?
