The same story happened to me (Turbotax Deluxe Desktop).
Rule #1. NYS E-file fails because you have to choose to E-file Federal Return first.
Rule #2. You cannot choose to E-file Federal Return because ... IT WAS ALREADY E-FILED 2 WEEKS AGO.
Rule #3. If you think that you are smart and still can make this work, try the Rule #1 again.
But there is a ray of hope:
I heard that the will be the software UPDATE around March 19, 2021.
TurboTax worked fine for me for many years. Not sure what happened to them this year.
