Sometimes Lacerte input requirements befuddle me...

I did a 1031 exchange in 2019 but the schedule E associated with exchanged the property proforma'd to 2020. I can select "delete this year" in the 2020 version but should I have selected "delete next year" in 2019.  

I just need input guidance on the correct method. Does it matter which way it is done?

TIA - we are all about to get really busy - again.
