Hola, @Martha146 ,
Hope all is well in Tijuana!
I am going with the assumption that you are filing US taxes, correct?
Given that you earned less than $20,000, Airbnb will not send you a 1099K, W2 or any other form. Essentially you are an independent contractor. See this help article:
https://www.airbnb.com/help/article/414/should-i-expect-to-receive-a-tax-form-from-airbnb
You can determine your gross and net earnings by going to your Transaction History; Earnings Summary. This will also tell you what you paid in Airbnb fees, which are tax deductible.

The Ernst & Young guidance is here:

I use Turbo Tax Home and Business. The software asks you questions and then walks you through the process, completing the necessary forms as well. It is worth the cost.
If you have more questions, feel free to reach out. Unfortunately I cannot give tax advice other than general information. Please use the @ sign with my name so that I will get a direct message from you. I just accidentally saw your question. 😞
I hope this is useful and that you are safe in Tijuana. Must be tough will the travel restrictions.
All the best,
Clare
