Filed Oct 2022, $29,538 Refund with 810 Freeze Code Since October - No Movement for 8 Months

Filed my 2021 taxes back in October 2022 and still nothing. When I check Where's My Refund it just says processing. I filed on Oct. 05, 2022 (which was the due date or return received date according to my account transcript) and it's been stuck ever since. I pulled my Account Transcript from the IRS website today (06-03-2023) and I'm trying to figure out what's going on. The transcript shows: FORM NUMBER: 1040 TAX PERIOD: Dec. 31, 2021 ACCOUNT BALANCE: -$29,538.00 ACCRUED INTEREST: 0.00 AS OF: Feb. 14, 2023 ACCRUED PENALTY: 0.00 AS OF: Feb. 14, 2023 ACCOUNT BALANCE PLUS ACCRUALS: -$29,538.00 From my return: FILING STATUS: Single ADJUSTED GROSS INCOME: $39,875.00 TAXABLE INCOME: $27,025.00 TAX PER RETURN: $3,924.00 The transcript shows these transactions: CODE EXPLANATION OF TRANSACTION CYCLE DATE AMOUNT 150 Tax return filed 20224405 11-22-2022 $3,924.00 76221-678-13759-2 806 W-2 or 1099 withholding 04-16-2022 -$2,064.00 290 Additional tax assessed 20211005 03-30-2021 $0.00 76254-999-05011-1 290 Additional tax assessed 20212605 07-20-2021 $0.00 76254-999-05031-1 810 Refund freeze 10-28-2022 $0.00 766 Credit to your account 04-16-2022 -$15,199.00 766 Credit to your account 04-17-2022 -$17,199.00 971 Notice issued 11-22-2022 $0.00 I'm really concerned about the "810 Refund freeze" code from 10-28-2022. Is this why I can't get my refund? What does this mean? The PROCESSING DATE shows as Nov. 21, 2022, but it's now June 2023 and still nothing. Called the IRS multiple times but can't get through to anyone. Starting to think my account is frozen because of that code 810, but idk how to tell for sure or what to do about it. Anyone else dealing with this or know what I should do to get my $29,538 refund?
