Made CSR request but cannot find the server/public.key that is made.

Anyone know where I can find it?

Nobody here can tell you because you've given no useful information.

What steps did you follow? What commands did you use?

If you had Fedora you may understand how to make a csr certificate and where it goes.

A CSR has zero to do with Fedora. CSR requests can be made on any Linux distro that has OpenSSL installed.

We can't help you if you don't tell us what you did. What we "understand" is not relevant.

The command

Code:

openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr

generates a private key. You can derive the public key from it:

Code:

openssl rsa -in server.key -pubout > server.pub

EDIT: After further reading, it seems that server.key contains both the private and the public key. If so, the second command just pulls the public key out of server.key. However, it should be possible to mathematically derive the public key from a private key (obviously not vice versa).
Also, as the other answers state, this has nothing to do with Fedora or even Linux. openssl is an open-source project whose code is used on many platforms including Windows.

Thanks I found it was in the same folder as the csr.
