1099-R Rollover from 401K to Roth $401K

Hello,

 

I rollover a 401K from a previous company company to current employer.  I learned that I went from a 401K to a Roth 401K.  However, Turbo tax gave me a picture of my income after entering all income and one of the line items is pensions - nontaxable, but over the left under the 2021 column it shows total amount of the rollover and it showing as income for 2021.  Why is this - see screenshot?  Why is a rollover considered income in this case?
