A:AnswerIt supports Sch. B but no longer supports Sch. C or Sch. D. This is new as of tax year 2014. I recommend using TaxAct instead this year. Their CD Version accommodates all schedules for a total price of $28. It can import prior tax year info. from TurboTax from the PDF format.
Premier is necessary for Sch. D ($20 more) and Home & Business for Sch. C. ($30 more).
A:AnswerUp to 5 but beware if you need to file a Schedule C, D, E, or F as you can't with this software anymore. H&R Block Deluxe is cheaper, does MORE and also allows 5 efiles.
A:Answeri have it installed on one computer and did mine and my daughter's federal returns from it. Our state has an efficient and free site to do state taxes so I only do the federal with turbo tax.
A:AnswerI'm not sure, but if you want to know for sure, I would call the manufacturer and it is Intuit. They have a good help line, look it up and it's on the internet. Good Luck
A:AnswerI buy the boxed version for usually $50.It covers up to 5 federal returns and 1 state return. Fed e-filing is free but state costs $20. We download the state, work it, then print it out. Our state does free e-filing at their website so I use the info from our printed return and key it on their website
A:AnswerI doubt Turbo Tax will support an older version of OS X. I hate to tell you this, but you are going to have to upgrade sooner or later or your Mac will become a security concern and you won't be able to purchase new software for it. There are some options from Turbo Tax at this link: https://ttlc.intuit.com/questions/2581940-mac-os-10-6-8-supported
