I’m getting a feedback loop when I’m recording vocals

I have iMac M4 running logic Pro X through a Tash cam model 12 mixer interface, when I record vocals, I’m always getting audio bleed into the vocal track, I turned my speakers off because I’m thinking I’m getting audio through the speakers and I still get the bleed after I turn the speakers off, I know it’s some setting, but I’m just lost on where it’s at, any help.
