What does the maximum deferral of Self-Employment tax payment mean? It could be a tax knowledge or Language barrier. If someone can explain this to me in Spanish, great!

I did some self-Employment side jobs like Interpreter and doordash, and now that I'm about to wrap up everything, Turbo tax is asking me about the maximum deferral? I don't get it. It could be a super dumb question, but I just don't get it. Can someone rephrase this to me or explain it in Spanish lol Thank you 🙂
