As a move-in incentive, my landlord gave me a $1000 gift card, and later sent me a 1099 misc reporting the $1000 as other income (line 3). Is this correct?

3. Select Wages & Income
4. Scroll down to Other Common Income and select the down arrow
5. Select Start next to Form 1099-MISC
6. Select Yes to Did you get a 1099-MISC?
7. Follow the prompts to enter your 1099-MISC
8. Enter the reason to Describe the reason for this 1099-MISC
