Tokarczuk told a news conference on Friday that she planned to use some of the funds to set up a foundation for the translation of literature.
She expressed "surprise that only two laureates, [herself] and Wole Soyinka have done that." Soyinka of Nigeria was the winner of the prize in 1986.
In addition to promoting literature, the foundation would also "investigate man and nature, what they have in common," Tokarczuk added. 
Animal rights is an issue "very close" to her, she said.
The lecture venue was the headquarters of the Stockholm-based Swedish Academy, which in October named Handke as the 2019 laureate, while Tokarczuk was selected for the 2018 award.
Handke on Friday declined to answer questions about his controversial stance on the Balkan wars.
The dual award announcement was due to a crisis that engulfed the academy last year, prompting the postponement of the 2018 announcement.
The two authors were to receive their Nobel awards on Tuesday at a ceremony in Stockholm along with laureates awarded in the fields of medicine, physics, chemistry, and economics.
Ethiopia's Prime Minister Abiy Ahmed Ali, the 2019 Nobel Peace Prize laureate, is to accept his award in Oslo.
Laureates also receive a Nobel medal and a diploma.
With the exception of economics, the prizes were endowed by Swedish industrialist Alfred Nobel (1833-96), the inventor of dynamite.
