Download State Program For 2020

Hello,

 

I purchased TT 2020 on DVD which included 1 free state program.  I need to amend this return (I am still within statute of limits).  I successfully reinstalled my 2020 porogram but cannot download state program for that year.  Since I paid for it (included in cost of disk) how do I download program?  (I switched computers and no longer have original program files). 

 

Thank you,
