2022 Tax Transcript Shows $1,761.96 Balance Due with Code 971 - Haven't Received Notice Yet

I filed my 2021 taxes back in March 2023. My transcript shows code 971 and 570 but idk what that means. I just checked my transcript today (06-17-2023) and I'm really confused and worried because it's been so long. Here's what my transcript shows: Internal Revenue Service United States Department of the Treasury This Product Contains Sensitive Taxpayer Data Request Date: 06-17-2023 Response Date: 06-17-2023 Record of Account FORM NUMBER: 1040 TAX PERIOD: Dec. 31 2022 ACCOUNT BALANCE: $2,761.96 ACCRUED INTEREST: $111.87 AS OF: Jul. 04, 2023 ACCRUED PENALTY: $108.65 AS OF: Jul. 04, 2023 ACCOUNT BALANCE PLUS ACCRUALS (this is not a payoff amount): $2,782.48 INFORMATION FROM THE RETURN OR AS ADJUSTED EXEMPTIONS: 01 FILING STATUS: Single ADJUSTED GROSS INCOME: $31,945.00 TAXABLE INCOME: $18,995.00 TAX PER RETURN: $2,940.00 SE TAXABLE INCOME TAXPAYER: $0.00 SE TAXABLE INCOME SPOUSE: $0.00 TOTAL SELF EMPLOYMENT TAX: $0.00 RETURN DUE DATE OR RETURN RECEIVED DATE (WHICHEVER IS LATER) Apr. 15, 2023 PROCESSING DATE May 29, 2023 TRANSACTIONS CODE EXPLANATION OF TRANSACTION | CYCLE | DATE | AMOUNT 150 Tax return filed | 20231905 | 05-30-2023 | $2,940.00 30211-456-78302-3 806 W-2 or 1099 withholding | | 04-16-2023 | -$310.00 276 Penalty for late payment of tax | 20231905 | 05-29-2023 | $117.30 196 Interest charged for late payment | 20231905 | 05-29-2023 | $114.66 971 Notice issued | | 05-29-2023 | $0.00 I see the 971 code which says "Notice issued" but I haven't received anything in the mail. The WMR tool just shows it's processing. I'm really confused about what's happening and why my return is taking so long to process. I thought I'd be getting a refund but now it looks like I owe money? Anyone else experienced this? Getting worried since it's been months now.
