After TT guides me through interview to calculate taxable amount for CSA1099R w/ blank box2, do I manually enter that amount in box 2a on TT site or still leave it blank?

You leave it blank as you enter the CSA 1099R exactly as it was received.

Then when you answer the questions, that follow the 1099R input, these answers will help determine how much of Box 1 gross pension is taxable to you.
