I am trying to e-file amended returns for 2019, 2020, and 2021 in Turbo Tax Premier. How do I get past the date restrictions when trying to submit?

The software did a great job calculating all of the corrections and preparing the forms for amended returns (Both Federal and State). However, I'm having issues trying to submit/transmit the files.
For the 2019 amended return - I'm getting an error "Correct Your Signature Date" and it wants a submission date prior to 12/31/20 versus today's date. (Same issue for 2020) 
For 2021, the error is "The Intuit Electronic Filing Center is closed for the 2021 Tax filing season".
I really don't want to file paper if e-filing is the preferred options!
Thanks!
