No UPS or USPS Shipping Modules in 1.50

[thirdmp]

New ZenCart installation, v 1.50

I am a new ZenCart user

My configuration manager doesn't have UPS or USPS shipping modules available. Here is a screenshot of my config manager's shipping modules :

I see all over the web tutorials that show more options. For example, the following is a config manager screen I saw in a tutorial. Clearly there are United Parcel Service and United States Postal Service modules which do not appear in mine.

What gives? I searched for UPS and USPS plugins and didn't see anything

Thanks,
