You didn’t trade any stocks, right? Because most of the complications are coming from complex tax situations not from simple salary earnings.
This is somewhat hyperbolic. Reporting income to the IRS is pretty easy. Dealing with deductions and credits is not hard, but is hard to get right. The whole process ought to be much, much easier than it currently is, but it is not "all but impossible". I even managed to teach all 3 of my kids how to handle 1099s and other stuff, and if they were a bit intimidated (they were), they didn't find it actually hard.
