Echo on Headphones or Delayed Sound

I am a beginner user of Audacity. My concern was about the echo coming-out in my headphones when I am starting to sing or talk. I am using Windows 10 and an audio interface. Headphones and xlr condenser mic are connected to the audio interface. Hope you could help me with this matter…

Thank you and more power…

What is the “audio interface”?
Where are your headphones plugged in?

In “Transport menu > Transport Option”, ensure that “Software Playthrough” is NOT enabled.
