How can I access and correct the 2021 tax returns I prepared on Turbotax, but never actually filed?

My husband's employer established a remote work policy for 2021 related to COVID. I initially created the tax returns without really knowing how to handle working from different states than the employer's state. I haven't filed the returns I prepared, and would like to correct the returns before actually filing them. Employer state, Arkansas. Working remotely from Kansas for 2021.
