I haven't used TurboTax recently, but I just received a check from my state's government saying that they've settled with Intuit over charging customers tax return services that should have been free.
This angers me greatly at how scummy TurboTax and Intuit have become over the years. For alternatives, I've been using FreeTaxUSA but I'm sure there are others that people can recommend.
Or God forbid a wash sale.
I tried my hand at trading options once (don’t do it kids) and ended up needing to mail 100 pages to the IRS (snail mail, like in an envelope)
That was my experience using robo advisors too, like betterment. I had so many buy and sells I had to mail my return in on paper, it sucked.
