How can I amend 2014 and earlier taxes using my mac pc?

[DoninGA · Accepted solution]

You will need to contact TurboTax support so they can push a Mac desktop installation file to your download account so you can amend your tax return.  Note that TurboTax only supports amending returns for tax years 2015, 2014 and 2013.

See this TurboTax support FAQ for a contact link and hours of operation - https://ttlc.intuit.com/questions/1899263-what-is-the-turbotax-phone-number
