I purchased Turbotax Deluxe last year and used it to complete my 2017 federal tax return on my MacBook Pro. I purchased the 2018 version of Turbotax Deluxe recently and when I tried to load it on my MacBook Pro, I got a message that said I couldn't load it as my OS/operating system was downlevel. I have a late 2008 MacBook Pro and it appears Apple is no longer allowing me to update my OS/operating system.
So my question above is whether I can use my 2017 version of Turbotax to complete my 2018 federal tax return. If not, is there a way I can complete my 2018 federal tax return on-line using the Turbotax Deluxe version which I have already purchased?
I'm not a technical person, so easy, step by step instructions are appreciated. Thank you!
