Thanks for the help @Clare0! Yes, it is helpful. Also, THIS was incredibly helpful, a tax-related document prepared for AirBnB; it has helped me determine what to do:

The booklet provides a flow chart and detailed description on how to distinguish what needs to be reported as taxable income and what doesn't:
"If you use a dwelling unit as a home and you rent it less than 15 days during the year, its primary function is not considered to be rental and you are not required to report the rental income and rental expenses from this activity. If you use a dwelling unit as a home and rent it 15 days or more during the year, include all your rental income in your income. Since you used the dwelling unit for personal purposes, you must divide your expenses between the rental use and the personal use as described earlier. The expenses for personal use are not deductible as rental expenses."
I rented my apartment for only 14 days last year, so I take that to mean I do not need to report my income (it was also nowhere near the $20k airbnb set as their minimum to receive a 1099). Very helpful, and this will be the document I turn to should any problems arise haha. Thanks again!
