Are these actions taxable? If yes, where would it go on the tax return (2021)

1. On February 15, 2020, Keith hurt his arm on a family skiing trip in Utah and was unable to fly for two weeks. He received $4,000 for disability pay from his disability insurance policy. He received the check on March 2, 2020. Flyby Airlines paid $600 in premiums on this policy during 2020. The disability insurance policy premiums are paid for by Flyby Airlines as a fully taxable fringe benefit to Keith (the premiums paid on his behalf are included in Keiths compensation amount on his W-2).

2. Jennifers grandmother died on March 10, 2020, leaving Jennifer with an inheritance of $30,000. (She received the inheritance on May 12, 2020.)

3. Flyby Airlines had space available on its Long Island, New York, flight and provided Keith, Jennifer, and their three children with free flights so they could attend the funeral. The value of the ticket for each passenger was $600.
