From my CPA: The 2020 trump CARES act will now let you carry the loss from 2018 back 5 years. We need to see if that is desirable. To do so we will need copies of your 2013-2017 tax returns. Carrying the loss back would be very beneficial for a high income person and not so much for a low income person.
Also allows the 2018 loss to show as a carry forward.
