This year is the first year I've worked at a company that has stocks, ESPP plans, etc. and I'm curious what's the most effective way to file my taxes by myself if I don't use TurboTax? I've read that Credit Karma Tax (which looks like it got sold again to Cash app?) doesn't do a good job covering these scenarios.
