turbotax business first time where to enter data for schedule M2?

using turbotax business first time for the 2020 tax year, it left schedule M2 blank. I guess since it had no previous tax data to work with? where do you enter the data that would end up populating the M2. In this case I had negative income for the 2020 year, i.e. line 21 is negative.

the 2019 return I prepared manually had a posative amount for the M2 ending balance, line 8
