Retirement tax questions

I converted a traditional IRA to Roth in 2020.  The box between lines 7 and 8 on the 1099-R  is checked and when inputting the "check" into TURBOTAX, it treats the conversion as a non-taxable event thereby reducing my tax obligation. 

 

Is the 1009-R form wrong, i.e. it should not have a check?  Or TURBOTAX treating the conversion incorrectly?
