Warning Message : Federal Capital Gains History

[mintie]

Have used UFile for many years.  First time experienced a warning on review titled Federal Capital Gains History  "The amount of capital gain deduction claimed in prior year is greater than the amount of eligible taxable capital gain.  The eligible taxable capital gains from prior years cannot be lesser than the capital gains deductions claimed"

I do not understand this warning.  I reviewed 2020 Capital Gain History Sch3, and all same except the addition of 2020.  Nothing new or different with capital gains this year that I am aware, only thing different was that I used the auto-fill from CRA.

Any suggestions on what I need to change to eliminate the warning message?

Thx
