I have two layers in AGOL: a county boundary layer for Nevada I got from census.gov and geocoded points (which I dragged and dropped a CSV with addresses into AGOL).
Going to each layer's options, there is no option to filter. Upon doing a search on the issue I came across this:
"You can create filters on hosted feature layers, ArcGIS Server feature service layers, and ArcGIS Server map service layers that have associated attribute data; you cannot create filters on map notes or features imported from a file."

Anyone know a way around this? I'm new to GIS in general.

Your layers must be a hosted web feature service to filter your data. It's my understanding that if you are not a member of an ArcGIS Online organization (i.e., you have an ArcGIS online public account such as those used with a home version of ArcMap) then you won't be able to manage a web feature service.
A workaround would be to sign up for a free ArcGIS Developer Plan to create web feature services. I was having the same issue and tried it today. Once you create your "Organization" you can add new items (including csv files) and create a hosted layer. Once that happens, you'll be able to use the filter capabilities on your new layer and create web applications with filtering drop-downs.
Just be aware of your "credit" limit when performing geoprocessing.
