Sold a rental, no form 4797 offered

Hi all.  I sold a rental and entered all the information and clicked sold rental property.  I didn't see a form 4797 and on my schedule 1, line 4 is empty.  After much googling I'm still confused.  Where do I put the sales price of the rental? Because right now all it shows is the loss (it was vacant all of 2020)  please help.  It's in pending so I have to amend
