I filed 2017 taxes on Computer A and 2018 on computer B. After filing my 2018 taxes, I needed to amend 2017. This was done on computer A since I can't find the CD to install it on computer B. The reason for the amendment was to add a business loss. This business was still open in 2018 so I need to amend 2018. How do I get the 2018 software to recognize the business that was set up in 2017 and other changes made on the 2017 Amended Tax Return?
