I don't know what method you used to reinstall your computer, but if it was from a backed-up disc image, it may have your 2023 program and tax files on it. But it won't if you installed everything like the OS and programs from scratch.
If you used desktop software in 2023 and do not have a backed up *.tax2023 data file or 2023 PDF due to reinstalling your computer, you can go to the IRS website and if you have (or can create) an IRS account, you can view/print/download your 2023 Federal tax return transcript for free.
If you want an actual copy of your 2023 return from the IRS, that costs $30 and can take "up to 75 days."
