Transfer Userform Data to Cells on Worksheet

Hello! I have been working on a spreadsheet, and teaching myself vba a bit in the process.
I have been able to get the basics of what I was trying to accomplish, which is to track projects, and have column a change color to represent
each stage of the project, as the proper field is completed going across the row.

I realized that this will get to be cumbersome, and decided it would be best to use a userform for entering new projects. I have spent hours today watching youtube tutorials, reading through web sites, and just cannot seem to figure out where to start.

I have attached the file to this post. Would anyone be kind enough to help me out? Once I learn something, I am very good at making the correlations and being able to adapt it, it just seems there are not a ton of well done tutorials on how to do this, rather more that show you an example that does not translate well into a different project.

Any help would be greatly appreciated
