ModuleNotFoundError: No module named 'requests' even after pip installed requests in Pycharm

Previously "requests" library was working, but I wanted to do a project and install a few libraries and "requests==2.22.0" was included among the libraries. After installing the libraries, I found out I get an error on PyCharm:

Traceback (most recent call last):
  File "C:/Users/User/Desktop/python/projects/youtube downloader.py", line 5, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

When I tried to install requests again using pip, I keep getting these errors, I also tried to uninstall requests and then re-install:

C:\Users\User>pip3 install requests

I noticed I have two? pythons in my computer, but I never got to know what I should do with two pythons (I use Ananconda for Jupiter notebook and PyCharm), and I'm assuming this can be the issue of why pip is not working as I expected... Or not. I am very confused.

++ So I found out in Jupiter notebook, I can import requests library without any issues, so I think I need to download the library in the other path???..

Can anyone help? Thank you so much in advance.
