Tax treatment of loss on spec home construction and sale?

Hi!  With a partner, we built a spec home in 2018/2019 and ended up selling earlier this year for about a $20,000 loss.  How do we account for the loss on our taxes and K-1s?  All three partners were actively involved in the project, either building or handling the banking/accounting/bookkeeping.  I'd like to do our own taxes and hoping it's fairly straightforward.  Thank you!
