Someone please help me fill out a W9?! Pleaseeeee I’m so confused

Imso confused on what this question means???? I have never filed a tax return, me and my husband filed jointly this year but he did it for me. I just started an only fans and I’m wondering what this question means ?

What do these 3 parts mean? Like it says account number (optional) does this mean put my bank account info???

And for the first question idk which is the right box to check
