The most cheap and efficient way to do your taxes is using Turbotax software. They have a very friendly user interface, and once you use them one year you can carry over all your info into next years for faster completion. The year I started using it, my uncle tried to do my taxes for me. He did it the old fashioned way, with pen and paper, and insisted there was no need to waste money on the software. I decided to try Turbotax in parallel, as an experiment to see if the results would be the same. In the end, it turned out that my uncle had missed a certain deduction that happened to only be available that year, but turbotax knew about it, and ended up saving me a few hundred more dollars. Been using Turbotax every year since.
