activation code for turbotax 2020

I am currently working on my 2021 turbotax return, and I wanted to see my 2020 turbotax return for some information, but the software says I need to enter my activation code???

 

I have already  completed and filed my 2020 tax return. including my state return...why is this happening??

I bought the software from Amazon, I have check my email, but there is no activation code that I can see.

I have the Amazon email, the order number, but no activation code.

Why is this happening when I have already activated, filed, and completed my tax return? Very frustrating...

Also frustrating is the support request for help process here... seems like very limited customer service!!
