IRS Verification of Non-Filing Letter for 2022 Taxes - What Does This Mean and Did Someone Request This About Me?

I got this letter from the IRS today and honestly im so done with this whole process. They keep sending me different letters with different numbers and codes, and I have no idea what any of it means. This latest one is from the "Internal Revenue Service, United States Department of the Treasury, MEMPHIS, TN 37501-1498" with a Tracking ID number and dated 06-18-2023. It's about my 2022 Form 1040. The letter says "Information About the Request We Received" and then states "On June 15, 2023, we received a request for verification of non-filing of a tax return." Then it says "As of the date of this letter, we have no record of a processed tax return for the tax period listed above." At the bottom it just says "If you have any questions, you can call 800-829-1040" and some website "sa.www4.irs.gov" Is anyone else getting totally overwhelmed by all this? It's like they want us to be tax experts just to file our returns. What does "verification of non-filing" even mean? Did someone request this about me? I thought I filed my 2022 taxes! Do I need to refile or something? Why would they send me this?
