Install old state on new computer

I am under audit for 2018 and needed to reinstall TurboTax 2018 (CD) on a new computer.  I am able to install and download 3 of the states I filed under but am not able to install the "free" state (NY) on my new computer because TurboTax will not download that state.  Since all the states are not downloaded, I cannot reopen my tax return.  When I called customer service, they said that they cannot add a state to my Intuit account older than 3 years (although I am able to download the states that I purchased that are older than 3 years).  Is there a way to add that "free" state (NY) so I can open my file?
