Is this a mistake?
 

I'm trying to learn a song, a fingerpicked version of Eva Cassidy's take on Over the Rainbow.

Here's my guide. https://tabs.ultimate-guitar.com/tab...ow_tabs_603162

It is the second-to-last note in the instrumental break. Shown as second fret on B string, it feels wrong.

If you've the time to look and try it, tell me what you think.

I have her "official" songbook (Songbook for Guitar) which transcribes the album version, the tabs you linked are close, but there's some different phrasing in the notation. Maybe your tabs is a different version, like from the live performance video? Either way, those linked tabs should work for you, best of luck to you in finding the music in the notes.

I'd agree that it's a mistake. Using that tab, I'd play the last three notes in the instrumental the same as the last three notes in the chorus.

Thanks! That's what I was doing, then trying it per the TAB thinking it was a turnaround, but it's not.
