Can't find Bookmarks Mac OS Sequoia

Hello, First my Q, then a comment. My bookmarks all show the same date. I can't find what I was going to use for work today because I can't find it in the bookmarks. This has happened frequently, more than not. Please help. On another note, I had said the YouTube commercial blocking wasn't working, but it is now on my Mac OS after changing some settings. Now I'd like to do that on my iphone 11 if possible. I can't seem to open settings the same way. Thank you.
