Step-by-step explanation:
In 2018 and 2019, Dorothy may deduct none of the net passive losses that remain after offsetting the passive income. In 2018, the $20,000 of passive income is used to absorb $20,000 of the $200,000 passive loss, leaving $180,000 of passive loss suspended. In 2019, the $40,000 of passive income is used against the $100,000 passive loss, leaving a $60,000 passive loss suspended for that year. Thus , a total of $240,000 of passive losses is suspended at the year 2019 into 2020.
