How to fill in Schedule D

I'm using Turbo Tax online for first time, I need to fill in Schedule-D to get carryover loss of $3000 from previous years, however for year 2020 I did not buy or sell any stock.  When filling in Schedule-D it asks me to fill in stocks that I sold but again I did not sell any?  how would I overcome this issue?  Since when I hit continue and finish it, it does not reflect the $3000 loss.  For your info, I filled in "Capital Loss Carryover" successfully.  Thanks
