I just deleted steam from my downloads but I accidently deleted the downloads section. how do I get the download section back?
I dunno what steam is but imagine it's some kind of an app or web page. Neither am I sure what you mean by deleting your downloads section. And we don't know whether your using a Mac, a PC, a Laptop, an Android, or whatever else.
If you're using a Windows PC my thought would be that you've deleted the Downloads folder. If so you can just create another one. Right click the appropriate spot, from the context menu select New, again select Folder, then when it's created just call it "Downloads".
On the other hand, if you do nothing I'd expect Windows would create another for you the very next time you try to save something to Downloads.
If that doesn't solve your problem, why not explain what you mean and give us some information about what you're using so that we can help you?
