Which turbotax products do I need to use? I'll have stock trade income, and bank interest income, and regular work income.
Can I use Free Turbotax production to file my tax for 2018? or do I have to use the one I have to pay for better version?
A tax return with stock sales would not be able to use the Free edition since to report those sales you need the full Form 1040, Schedule D and Form 8949. In tax year 2017 you would need to use the Premier or Self-Employed online editions to report the stock sales. The assumption is that this will also continue for tax year 2018.
Or you could use any of the TurboTax desktop CD/Download editions since all the desktop editions support stock sales.
(be careful if buying from anyone else though....some Deluxe's do not include a free state download)
None of the online software versions have a free state included.
you do not have to buy through intuit. Amazon, Costco and other reliable sources may offer the same version at a cheaper price. beware of some websites, what they offer and what you get may not be the same. and may even be unusable
