Can't find previously imported deck

I’m having issues finding a previously imported anki deck. I had a friend re-send me the deck and I tried to import it again but anki keeps saying “notes skipped because already in file”. However I’ve looked within every deck I have and I cannot find these cards. This might be a novice question but is there an easy way for me to search for a deck? I already tried to do it in the browse section and still couldn’t find it. Any help would be appreciated, thank you!

You can use File>Switch Profile to create a temporary profile and import into it. If you take note of some of the card content, you can then return to your normal profile and search for the content to locate it.
