Why do you refuse to pay someone?
My parents both worked for the IRS for the entirety of their careers. I have access to assistance, which I've used, but I like to know the in's and out's of all of this. Also, I am unbelievably cheap.
When I bought my first car, I broke down every single cost, fee, calculation, etc. into an Excel spreadsheet so I understood where every dollar went. I did the same thing with my paycheck. When I finished my basement in my old house, I got some people together and acted as my own general contractor and subbed out whatever I couldn't do. It helps me learn where to optimize and understand where every dollar goes.
In this instance, I read the tax preparation guides for Kansas and Missouri, and I filled everything out accordingly based on the software after that. The guy from the Kansas DOR basically said I'm doing it right, but just to be prepared that whoever works it on their side may screw it up, so I probably need to be ready to back it up with a tax advocate if necessary.
