I am having the same problem. I'm using Turbo Tax Premiere for 2020 tax year. I have tried a variety of passwords, all within the prescribed limits, but I keep getting the same message over and over:
"For security reasons, your answer should be between 6 and 16 characters long, not including any spaces"
I have used turbo tax for years and have never had this problem before. I am using the same computer as I used last year and I was able to encrypt save my 2019 files with no problems.
