I am trying to catch up in my filings and was hoping to use TurboTax Business Incorporated. Is there a version that can file a Feb 2018 return available now?

Hi Thank you for using Intuit TurboTax AnswerXchange

Previous year versions of TurboTax Business Incorporated for T2 returns can be purchased for prior years at the following link:

https://turbotax.intuit.ca/tax-software/prior-year-taxes.jsp

The 2017 version of the software would allow you to prepare and file a T2 with a year end of Feb 2018, ( This version allows preparation of year ends form November 1, 2017 to October 31, 2018)

Other prior year returns are also available at the above like

Hope this helps
