I tried to factory reset my macbook air 2013 but I accidentally deleted the wrong disk and now I have os x yosemite, and I have no idea on how to get it back or even know if its fixable. If someone can please help me, thank you!!

It can be that you have to install Yosemite first, then to High Sierra and so back to Big Sur. You can try and download and install macOS here

Or perhaps Yosetime to Sierra to Big Sur.
I believe Sierra is the last version of the OS for which Apple provides a direct link to a .DMG file. For High Sierra and later, the links bring up hidden pages in the App Store. If Yosetime couldn't open the App Store links, even trying to jump to High Sierra might be one OS too far …
